Productivity Soars With CNC Machines

CNC machines can be a lifesaver in an industry setting. They speed up work in those tedious jobs that seem to never end. Although they can be a bit pricey new for solo use, you can put one to work on your wood working room for around half the price if you buy used.

About CNC Machines - How Do They Work?

CNC machines, aka Computer Numerated Control machines, are mechanical drillers, in a nutshell. When they are programmed properly, the CNC equipment can produced drilled holes in record time. This technology first hit industry in the 1970s and turned manual labor on its head. Production times were reduced significantly by this milling machine.

The reason CNC machines were so revolutionary is because they could complete the work of many human drillers in record time, and the work they were produced all but eliminated human error. Many industrial industries rely upon CNC equipment every day.

CNC Machine Types

If woodcutting is your thing, a CNC lathe is the way to go. This machine can cut your wood in any width and shape you want with minimal error and incredible speed.

For a milling machine, a Bridgeport machine is the best choice. Although these machines are extremely pricey, they can also make milling significantly more productive.

CNC machines can also be used for engraving. They can engrave on nearly any surface, and with the right programming, they can engrave a huge variety of different fonts, letters, and designs.

CNC Machines on a Budget

These machines might be ultra productive, but most individuals could never make enough use out of them to justify their hefty price tag. However, if you have a small but growing business, a CNC machine could take you to the next level. Buy used, save big time, and watch your profits grow.

Refurbished CNC machines are even cheaper than ones that are merely used but have never had any problems. A refurbished machine is one that has been repaired by a professional, and the extent of the repairs will impact the price you can get on one. You don't have to fear these refurbished machines because they have had a few problems in the past. In almost every case, a refurbished machine will come with a warranty that will give you peace of mind about your investment. Shy away from those "buyer beware," no warranty type of packages. A good refurbisher won't mind backing up their own work.

32mm CNC sliding head auto is world's

Citizen Machinery claimed to have the world's fastest 32mm capacity CNC sliding head automatic lathe, which will be in action during Open Days this October.

Citizen machinery UK will be launching, what it claimed to be the world's fastest 32mm capacity CNC sliding head automatic lathe at its CNC Autumn Productivity Days Open House The Open House will be staged at the Bushey, Watford, showroom October 7-9, 2008.

Managing director Citizen machinery UK, Geoff Bryant said that the event will be the first chance to see the production version of the Citizen A32-VII in action.

He commented: "So impressive was the prototype machine shown to visitors at the MACH 2008 exhibition in April at the NEC that six advance orders were placed on the stand at the show".

With deliveries about to commence, the machine will be set to produce sample components using its up to 27 tool capacity and sub-spindle capability.

It will demonstrate high metal removal rates from its heavier construction and 40% increase in spindle torque, coupled with ultra-quick 45 m/min rapid traverse rates.

Also, contributing to the minimisation of non-cutting times, Citizen's 'Streamline Control' software will show the benefits obtained by its ability to co-ordinate axis overlaps with direct C-axis indexing and shorter start up and switching times.

The Open House will provide visitors an opportunity to see how to upgrade their productivity by viewing another seven CNC autmatic lathes in action.

These will include the following.

* The high speed linear driven RO7.

* A mid-range K12 and larger capacity K16.

* The L20 plus.

* The low cost A20 - a highly productive smaller 20mm capacity version of the A32.

* Two top of the range M-Series machines, an M16 and M32, will also be under power.

Supporting companies at the event and showing related CNC sliding head technology products of interest to the small turned parts industry, will include the following.

* Delcam with CAD to CAM.

* Floyd Automatic Tooling.

* Iemca bar feeds.

* Miyano Machinery UK.

* Renishaw.

* Sandvik Coromant.

Citizen Machinery's high pressure CoolBlaster system will be fitted to several machines and its UK developed CNC Wizard programming software, CNC Program Editor and wireless program transfer will be demonstrated.

CNC targets multi-spindle automatic lathes.

SIEB & MEYER USA Announces 8th Generation CNC and Machine Control Platform for Multi-Spindle Automatic (MSA) Lathes


Provides OEMs, specialty machine builders, and retrofitters with a high-performance, all-digital machine control platform. We offer specialize applications for Acme, New Britain, Warner & Swasey, Euroturn and Gildemeister MSA lathes

Cincinnati, Ohio - SIEB & MEYER USA introduces its 8th generation CNC and motion control platform for Multi-Spindle Automatic (MSA) machine tools. This next generation CNC provides a sophisticated blend of industrial hardened technology with the advantages of a PC-based control that has seen business activity triple in 2008. Part lot sizes are smaller today, tolerances are tighter and the traditional screw machine shops must have more flexibility. CNC control of the machine is the solution to reduce setup time, add single point threading and improve accuracy. Other benefits include data collection, machine network connectivity, remote diagnostic service support and more.

"We are moving 1960's screw machine technology into the 21st. century and are very excited to offer this new platform to the industrial automation community," said Jay Endres, SIEB & MEYER USA, President. "We have leveraged our 37 year history to deliver a solution that provides OEMs, retrofitters and manufactures with a control that is easy to install, uses standard hardware components, and delivers superb performance."

CNC laser offers high cutting speed and

Subcontract fabricator has found a CNC laser cutting machine that is not only able to handle the wide-ranging job specifications, but also offers speed, reliability and the highest cutting quality.

Young and Wood of Harlow, Essex, UK, makes a diverse range of components for architectural fittings, commercial buses and the banking industry The company recently installed a Syncrono laser cutting machine from Prima Industrie to keep production costs down and remain competitive
Young and Wood director, John O'Rourke, said that versatility is a key requirement as in the morning the company could be producing bus components, and in the afternoon, banking trolleys.

He explained: "It was vital we invested in a machine that was not only able to handle the wide-ranging job specifications, but also offered speed, reliability and the highest cutting quality".

Young and Wood works in a range of materials between 1mm and 15mm thick, including mild steels, stainless and aluminium The company sought machine that could cut heavy and light gauge material to the standards required. Six years ago the company added a Platino laser cutter from Prima to its machine park of mostly punching machines.

Young and Wood typically profiled up to 15mm thick mild steel, 8mm stainless steel and 6 mm aluminium sheet on the Platino, which provides 0.03mm cutting accuracy across its 3 x 1.5m machining envelope.

Superior dynamics enable head speeds of up to 140m/min and accelerations of 12 m/s2 to be achieved.

"The Platino's ability to pierce material in around 0.5s and cut at up to 6.5m/min has substantially reduced cycle times and increased our productivity, enabling us to minimise the effects of escalating raw material costs," reported O'Rourke.

"The machine's accuracy and repeatability has allowed us to manufacture a much wider range of products than is possible with our punching machine set up".

* Raising productivity - impressed with the Platino's versatility and the high level of support and back-up from Prima, O'Rourke decided to exchange it for a Syncrono in order to benefit from the further improvements to productivity and efficiency that it offered.

O'Rourke continued: "Prima has always responded quickly when we have needed assistance and that is so important for us, We had a few teething problems to overcome - which is to be expected with a piece of kit newly introduced to the market.

But it was the excellent service as much as the speed and accuracy we would get with the Syncrono which motivated us to invest in another Prima laser machine".

The Syncrono produces very fast processing times, enabling more than 1000 holes to be cut in 1 min.

While a job carried out on the punching machines typically took around 14s to complete, Young and Wood has been able to achieve the same operation on the Syncrono in just 4s (with nitrogen) and 6s (with air).

A major benefit for the company is the Syncrono's adjustable optics, which provide fast speeds and extreme precision, irrespective of the gauge of metal being machined.

"This feature really sold it to us in view of the wide range of materials and thicknesses we deal with every day," said O'Rourke.

"Syncrono's modular construction and versatility ensures we can machine all of our jobs with confidence and have the flexibility to meet future production requirements".

O'Rourke concluded: "We currently utilise a shuttle table, which, at the end of the day shift, automatically switches over two plates.

This is sufficient to feed the machine to enable 'lights out' operation.

However, we plan to install Prima's automatic Compact Server stacker/destacker in the near future.

Controlled directly by the Syncrono, this will enable us to handle an increased volume of work overnight".

* About Prima Industrie UK - Coventry-based Prima Industrie UK draws on the established track record of its Italian parent organisation, Prima Industrie, a world leader with 30 years experience in the design, development and manufacture of laser cutting machines and automation solutions.

Universal tool presetting system is optical

Schunk has introduced an optical tool presetting and measuring device for all conventional tool clamping systems, and can increase productivity in metal-cutting operations by 15%.

Schunk's TRISet optical tool presetting and measuring device can measure, check and adjust tools before using them The TRISet is suitable for all conventional tool clamping systems

Also, a Schunk Tribos clamping device can be optionally integrated to enable Tribos tools to be length set, clamped and measured in seconds.

The TRISet allows users to significantly increase machine running times and reduce machine down time caused by tool setting.

Tools can be clamped, measured and adjusted outside the machine while the CNC machine continues to manufacture parts, delivering significant time savings.

* Polygonal clamping technology - the Tribos polygonal clamping technology is especially suitable for tool presetting.

Schunk told manufacturingtalk that when compared with other toolholding systems, no axial displacement arises with the Tribos system.

The reason is because clamping occurs in the radial direction only.

The TRISet tool presetting system increases productivity in metal-cutting operations by 15% because the use of preset tools increases machine running times.

It also prevents reject components as even the first workpiece is machined to the exact size required with no deviation caused by the tool.

The Schunk TRISet offers the option of adjusting tools with exceptional precision using measurement programs for certain measurement tasks and checking the quality of the cutting edge.

Tool presetting enables micron precise tool measurement and this allows inspection of the cutting edge wear and edge quality.

The system also caters for measurement programs that monitor radial and axial run-out that determine the 'highest cutting edge' and 'largest diameter' dimensions.

* Menu format - a menu format simplifies operation considerably.

ImageController1 image processing allows length and diameter, as well as cutting edge angle and cutting edge radius, to be detected within seconds.

The setting devices are available in two measuring ranges with a range of measurement Z = 400mm and D = 400mm or a measuring range of Z = 600mm and D = 400mm.

To ensure quality over the long term, the Schunk Tribos presetting device depends on high-quality components, such as the following.

* Heidenhain measuring systems.

* THK guidance.

* Bosch pneumatics.

* Computers from Sirius.

The tool mounting spindle has 4 x 90 deg indexing and 360 deg brake as well as the integrated calibration edge.

* About Tribos polygonal clamping technology - the Tribos polygonal clamping technology was patented and developed by Schunk in 1997 and is based on a polygonal shape of the clamping bore.

In unclamped condition, it has a polygonal cross section.

If an exactly defined external force is applied to the clamping side of the toolholder, the clamping bore will deform.

The toolholder shank can now be introduced into a larger, circular bore.

After this force is removed, the clamping bore will return to its original shape and will clamp the tool shank.

Within seconds, the tool is changed using a hydraulic clamping device.

The Birth of the Virtual Machine, a Quest for Hybrid CAD

Archimedes, a classical mathematician who died 2,200 years ago, is about to become part of the PLM (product lifecycle management) lexicon.

Soon after the ink dried on its acquisition of UGS, Siemens' Automation & Drives (A&D) division began working on a project dubbed Archimedes. Discussing it in the company's internal publication titled Pictures of the Future, publisher Arthur F. Pease wrote, "Siemens' recent acquisition of UGS has given its [A&D] Group ... the tools to merge the real and virtual worlds of production" ("Factories of the Future — UGS and Siemens," Fall 2007). For more on the Archimedes Project, read "Event Report: [2007] UGS Media/Analyst Conference."

At Siemens' 2008 media and analyst briefing, which took place in Boston, Massachusetts, in May, Michael Weyrich, leader of new-generation business at Siemens A&D, introduced tangible evidence of Archimedes in operation. By marrying UGS's NX to Siemens' motion-control capabilities, Siemens has developed the Virtual Machine, which connects CAM (computer-aided manufacturing) to CNC (computer numerical control).

CNC Behavioral Science
Generally, a CAM program simulates the machining operations by animating the machine's movements based on kinematics, the mechanical motions predicted based on physics. However, in the physical world, the CNC operator uses a controller attached to the machine to perform the required tasks.

"In the Virtual Machine, NX takes into account the unique machine-tool characteristics of the real machine's controller," Weyrich said, "so information like how a machine is configured on a certain shop floor, for example, will be part of the simulation."

With Siemens' Virtual Machine, the simulation process is driven not only by kinematics but also by the motion algorithms used by an actual 840D controller. Therefore, it is expected to faithfully depict the cutting conditions, axis movements, collisions, work piece geometry, and motion behaviors of the machine tools equipped with a Siemens 840D control.

The virtual machine can physically be found at INDEX, a CNC machine supplier headquartered in Esslingen, Germany. It is now part of what the company delivers to its customers along with the physical hardware.

figure
The Virtual Machine, a use-case scenario derived from Siemens' Archimedes Project, produces accurate simulation of machining operations by incorporating the controller's algorithm.

E4DF
Wolfgang Schloegl, Siemens' digital factory team leader, followed Weyrich's virtual machine presentation with another that focused on the virtual factory, or E4DF (engineering for digital factory). In his view, the major shortcomings in today's engineering are:

* unsynchronized processes
* redundant data entry, processing, and storage
* insufficient validation of engineering results

His recommendation? Use Siemens' SIMATIC Automation Designer software along with Teamcenter as the data backbone. In its online literature promoting SIMATIC's openness as an advantage, Siemens states, "The previously separate worlds of mechanical components, electrical systems, and automation are now represented transparently in one plant structure. This guarantees data consistency. The result is that existing software tools can easily be used again and combined with SIMATIC Automation Designer."

With SIMATIC, CAD diagrams form the basis for plant layout. Once read into SIMATIC, they become the touchstones for configuring the production process. "The product has been field-tested for 1.5 years," said Schloegl. "It's now ready in a way that we can sell it."

By the end of this month, SIMATIC 3.0 should be available, along with E-CAD Extension Packages for automatically generating and integrating circuitry design. Schloegl revealed that SIMATIC will begin using JT, a lightweight file format developed by UGS, for visualization of factory components in 2009.

Live Rules Overrule Feature History
Synchronous Technology, Siemens' answer for combining freeform and parametric modeling, had been in incubation in a development lab at UGS before the acquisition. "When Siemens found out we had been working on this, they were delighted," said Chuck Grindstaff, Siemens' executive vice-president of products. With Siemens' contribution to the R&D budget, Synchronous Technology swiftly made its debut last month (for more information, read "Siemens Breaks Free from History".

In the first quarter of 2008, three history-based CAD vendors — Dassault, PTC, and Siemens — unveiled their own solutions that allow CAD users to employ a mix of modeling approaches. In February, PTC introduced a new version of Pro/ENGINEER that incorporates certain freeform-modeling features from CoCreate (acquired by PTC in October 2007). In April, Dassault previewed CATIA Live Shape, a freeform-modeling module for CATIA users.

Evan Yares, a CAD industry veteran in attendance at the Siemens event, said that what CAD vendors are pitching as freeform modeling may be described more accurately as "feature-imprint modeling."

Unlike the freeform-modeling methods found in software programs widely used by animation artists and game developers (such as Autodesk 3d Studio Max or Maya), the method now making its way into CAD packages relies on the recognizable topology of mechanical features (holes, tubes, and shafts) and makes every effort to retain the surface and geometric relationships. Therefore, Yares argued, the deformation is based on the existing imprint of a feature.

Synchronous Technology relies on Live Rules, a set of algorithms for detecting and recognizing standard mechanical features, to let the software intelligently reshape the affected geometry in response to a user's pushes, pulls, and dimension-driven changes. Live Rules can be disabled when a user wants to make an unorthodox change that might break the generally accepted associativities and constraints in a feature. Conversely, users also have the option to place locked constraints (or parameters) on a model.

In the demonstration, Dan Staples, director of Solid Edge product development, demonstrated how one can use Synchronous Technology to edit a Solid Edge assembly containing a SolidWorks part and an Inventor part. The new releases of NX and Solid Edge (dubbed Solid Edge with Synchronous Technology, or SEST for short) both feature Synchronous Technology.

figure

figure
Siemens promotes upcoming releases of NX and Solid Edge with Synchronous Technology as CAD tools with the potential to offer dramatically higher productivity in multi-CAD environments.
Other Highlights
NX 6 features Product Template Studio, a way to publish a simplified parametric model from a complex part as input. The tool is designed to let users automatically generate a brand new part based on an existing one through guided input fields, bypassing the need to directly interact with the geometry.

With NX 6, using the mix-mesh approach, a user can prepare a mesh model for analysis with different mesh densities for different regions. The tool is particularly useful when dealing with products with a mix of simple and complex curvatures or a combination of thick and thin surfaces.

Throughout the last several years, digital prototyping has become the new mantra for CAD and PLM vendors. It's an ambitious vision, wherein everything taking place on the factory floor — from the tilt of an automatic drilling arm to the posture of an assembly worker — is simulated with digital replicas first. Siemens' progress report on the Archimedes Project proves that having a hardware giant for a parent company can be an advantage.

Stiffer CNC turning centres up metal removal rates

Considering resonant frequency, Index-Werke has redesigned of CNC turning centres to reduce vibration and double the machine structure stiffness to maximise metal removal rates.

Index-Werke noted that the higher the resonant frequency (RF) of a machine tool's structure, the greater is its inherent stiffness Consequently it becomes more difficult for machining forces to induce vibration

So Index has redesigned its patented SpeedLine C-type CNC mill-turning centres to increase their RF above that of all other lathes on the market.

Geo Kingsbury Machine Tools, launched the machines in the UK at the recent MACH 2008 machine tool exhibition.

Using the RF measure, the Index C-type lathes are over twice as stiff, or rigid, than the existing Index G-series models of equivalent capacity.

The company said that there is more scope for finding the 'sweet spot' for any combination of toolholder, cutter and workpiece material.

The design allows depth of cut to be increased for maximum metal removal rate.

* Improved surface finish - as well as increasing productivity, the increased rigidity and lower machine tool vibration also ensure good surface finish of the machined part, said Index, as well as prolonging tool life and reducing noise.

Index said that better damping leads to higher accuracy machining, even for strenuous applications involving intermittent hard turning and reaming.

The SpeedLine C-type 42mm and 65mm bar automatics, when launched in 2005, were the first in the world to replace conventional compound turret slides with two interconnected steel plates sliding directly over the machine bed.

The recent redesign of the range has seen these machines improved and two new models introduced with 30mm and 90mm bar capacities.

The defining characteristic of the lathes that provides such high RF and stiffness hinges on the actuation of the turrets.

Each is mounted on a front plate while an interconnected rear retaining plate is driven kinematically from behind the machine bed.

The critical advantage is that the distance between the turret centreline and the point at which it is driven is much shorter than for a compound slide.

Up to 14 tools can be used in each of the three turrets in the following manner.

* Turret 1 moves in X-,Y- and Z-axis above the spindle centreline and works at the main spindle.

* Turret 2 mounted below the spindles operates in X-, Y- and Z-axis at either end.

* The motion of upper turret 3 is restricted to the X-axis and works only with the counter spindle, which moves in the Z-axis.

Three tools can be in cut simultaneously for high productivity.

There are two sizes of machine frame, designated C100 and C200.

The former is the 'host' for the 30mm and 42mm bar capacity spindles and the latter (shown at MACH 2008) is for the 65mm and 90mm spindles.

Distance between the main and counter spindles is 510mm and 710mm respectively.

All models are fast, with 1G acceleration in X- and Z-axis up to 60m/min for the smaller machines and 50m/min for the larger models.

CADDIT Localizes T-Flex for Australia, New Zealand

CADDIT announced release of the T-Flex CAD/CAM/CAE CNC software platform to Australia and New Zealand. T-Flex seamlessly integrates complete parametric 3D solid, surface, dynamic motion modeling and FEA into one single easy-to-use program. T-Flex also offers extensive CNC manufacturing tools for milling, lathe turning, wire EDM, drilling, etching and laser cutting.

After twenty years of major development, T-Flex CAD, CAM software is fully emerging onto the global CAD market. The unique T-Flex hybrid, Parasolids-based solid-surface modeler offers designers special ability to apply free-form modifications to their parametric designs. Freeform modifications are then added to the file history and can themselves then be changed parametrically. Sketches are created using an intuitive system of construction vectors and parametric expressions. Users migrating files from SolidWorks, Solid Edge or Autodesk Inventor can read these models directly into T-Flex without the use of STEP or IGES. T-Flex CAD also includes both the FEA and Dynamics Express modules for lightweight model simulation and kinematics. But this entire package still costs just a fraction of similar functionality from the other mid-range CAD programs.

T-Flex integrated CAM software manufactures the designs created or imported in T-Flex CAD. Users enjoy fully-associative multi-axis milling, punching, lathe turning, drilling, engraving, wire EDM, flame and laser cutting. Precise mould and die, core and cavity, insert and slide machining can be finished from the same interface with a wide variety of CNC secondary operations. Custom post-processors and user-definable tools allow machinists to specify virtually any cut. Integrated 3D post-processing allows machinists to verify the final associative, parametric toolpath.

Many businesses require CAD CAM software that is affordable, fast, flexible and easy to use. T-FLEX is best utilized in a creative design department that is under pressure to produce high quality scale drawings and/or solid models with rapid turnaround. Products that are subject to frequent geometric changes are ideal. T-FLEX can easily produce dozens of new drawings/models per hour, complete with documentation, from a single parametric model. T-FLEX can also be used as general purpose 2D and 3D MCAD software. It includes everything required for the professional design.

“We believe T-Flex CAD CAM Software is a good fit for Australian engineers. It’s fast. It’s flexible. It’s inexpensive,” Ben Decker from CADDIT explained. “The CADDIT.net website demonstrates this a little, but the best is for companies to try it for themselves before going into something more expensive. They can download it free from us and try it for a few weeks without obligation.”

CNC Programming System Poised for International Growth

Software developer SmartCAMcnc increases international representation of SmartCAM software

EUGENE, OREGON - 3 March, 2008 - SmartCAMcnc, the exclusive developer of SmartCAM computer-aided manufacturing software has announced that it is to increase international representation and sales of the company's flagship SmartCAM suite of CAM system software.

Hugh Caldwell, Vice President of Sales & Marketing, remarked "SmartCAM is rightly recognized as one of the industry's premier CAM systems with a proven pedigree established over the past 25 years. Our USA sales team and existing international dealers do a great job, and the globalisation of design and manufacturing of the past decade presents us with new and increasing opportunities within many the regions of the global manufacturing economy. We needed to acquire a seasoned leader to assist our long-term international expansion."

To that end, the company has appointed Terry Antrobus, an experienced CAD/CAM professional, to head the development of international business. "We are delighted to have brought on Terry in the new position of International Business Development Director to manage our overseas business," continued Caldwell. "Terry has broad, invaluable experience in the development, sales, promotion and commercial support of CAM sales partners. It is an exciting time for SmartCAM, and I look forward to working with Terry as we make new friends, dealers and contacts around the world."

Prior to his CAD/CAM system sales experience in the late 1980s, Antrobus began his career as a production engineer programming CNC machines, and later held CAM support roles with a software provider. He relishes the opportunities presented in the new job: "I have always been enthusiastic for CNC machines and machining, and in particular am a strong advocate of the use of computerized techniques for programming. Good off-line systems are always a benefit for any CNC production process - today's systems more so than ever - and I am excited by the prospect of working with the highly-regarded SmartCAM product, as well as our dealers and customers around the world."

Antrobus has sold and supported SmartCAM in the past and recalls how impressed he was with his very first experience. "As part of the first sales team responsible for introducing SmartCAM into the UK, my first CAM sales position involved selling SmartCAM alongside CAD software. I clearly recall being highly impressed at the system's advanced functionality and simplicity of use, which had become apparent after only a few minutes of the introductory presentation. It was difficult to understand how such a substantial solution was available at a very competitive price. Much later I was quite pleased to learn that SmartCAM continues to be available and affordable, and that I had an opportunity to be directly associated with it."

Opportunities for SmartCAM sales partners and distributors are available in many regions around the world. Antrobus went on to say, "SmartCAM is ideal as a primary CAM system, and can also be useful supplementing existing products within alternative and new applications areas. I look forward to contact from new or existing businesses interested in working with our SmartCAM solution, and to exploring the many possibilities available."

Affordable robotic bending cell is easy to operate

The first showing of a competitively priced, automated robotic bending cell will demonstrate its easy operation and programming for small to medium sized sheet metal components

LVD said it will be concentrating on 'cost-effective' sheet metal working automation and integrated sheet metalworking systems at the UK's MACH 2008 machine tool exhibition. LVD will exhibit two machines never exhibited in the UK before, including one making its world debut. * Affordable robotic bending cell - making its world debut the LVD RoboCell automated robotic bending cell offers affordable automated bending.

LVD told manufacturingtalk.com that the cell combines the company's extensive press brake bending technology and Kuka robotic material handling integrated under an off-line LVD CADMAN software system.

Competitively priced against other robotic bending cells in the market, LVD said its RoboCell is easy to operate and program.

The cell is ideal for companies looking for affordable automation of the bending of small to medium sized components.

Flexible and intuitive RoboCell enables the operator to move from 'art to part' faster and with fewer interventions than other conventional robotic bending cells, said LVD.

* CNC laser cutting - complementing the new RoboCell, the LVD Orion 3015 plus CNC laser cutting machine is complete with automated autoload unit and makes its UK debut.

LVD said that the Orion 3015 Plus is ideal for subcontractors or OEMs, which require a compact and value minded automated laser cutting solution.

Speed up quality checks in CNC machining

To speed up quality control routines in CNC machining, a tool recognition system can detect broken tools in under a second, while a radio transmission probe reduces inspection times

Renishaw will present at the UK's MACH 2008 machine tool exhibition products and training initiatives that will help businesses to reduce process times and minimise quality costs for a wide range of machining and measurement applications. Renishaw will be quoting two very different, but highly successful UK companies that are fighting back against overseas competition through a commitment to the latest technologies, and a tight focus on process control.

This contribution to speed is demonstrated by BK Tooling, which has just five employees, yet is successful in the highly competitive mould and pressure die-cast tools market.

Using Renishaw touch probes to automate part and tool setting, jobs can be changed over rapidly, and costs reduced by maximising machine up-time and eliminating scrap, said Renishaw.

* High-quality parts at competitive prices - a further example is provided by Martin Aerospace, which has recently won a new contract with Rolls-Royce owing to its ability to provide high-quality parts at competitive prices.

At its Lanarkshire factory the use of high-accuracy Renishaw touch probes and complementary inspection software, has reduced floor-to-floor times significantly.

This technology has also enabled strict process control regimes to be introduced, allowing the company to maintain very tight tolerances and reduce scrap on complex inconel parts.

Addressing the UK skills shortage * Skills shortages - based on its years of manufacturing experiences, both from its own factory and the many thousands of probing applications at customer sites, Renishaw has developed a training course based around a concept called the Productive Process Pyramid (PPP), which aims to help address the UK's shortage of skilled engineers.

A network of Renishaw Productivity Centres (RPC) will be developed to deliver the courses, where students will be exposed to the principles and practical aspects of the PPP.

PPP is used to systematically identify and controls sources of variation in machining processes, and tackles topics such as design for manufacture, the control of process inputs and environmental stability.

The West Midlands Manufacturing Measurement Centre, based within Coventry University, has been announced as the first RPC, and will commence courses in Spring 2008.

* New products - at MACH, Renishaw will show, for machine tool applications, its TRS2 tool recognition system.

The TRS2 takes typically less than 1s to detect broken tools.

For users looking to reduce inspection times by measuring complex 3D part geometries on all sizes of machining centres, Renishaw's new RMP600 compact, high accuracy touch probe with radio signal transmission, is a powerful solution.

Also being demonstrated is Renishaw's twin-probe system, which uses a single optical receiver for tool setting probes together with a spindle-mounted touch probe for component inspection, offering fast integration.

This will comprise the OMP40-2 touch probe and Renishaw OTS cable-less tool setter, which is particularly suitable for machines with twin pallets or rotary tables.

* Compact laser interferometer - for visitors to MACH 2008 looking to optimise machine performance, the Renishaw XL-80 is a compact laser interferometer measurement system.

Renishaw told manufacturingtalk that it combines portability, performance and ease of use for calibration routines.

* CMM developments - for CMM users, the revolutionary REVO 5-axis measuring head and probe system can improve inspection throughput levels by up to 900% on machines previously fitted with 3-axis scanning systems.

* machine tool builders - for designers within the machine tool industry, Renishaw's SiGNUM non-contact RESM angle encoder has a large through-hole making it ideal for high-speed feedback on machine tool rotary axes, and is now available with FANUC serial communications.

For applications that require the highest accuracy, the REXM angle encoder offers new levels of angular metrology, with better than +/-1 arc sec total installed accuracy, zero coupling losses and exceptional repeatability.

Device measures and presets tooling optically

A highly accurate optical tool presetting and measuring device can clamp, measure and adjust tooling outside the machine while the CNC machine continues to manufacture parts

Schunk has introduced its highly accurate TRISet optical tool presetting and measuring device. The TRISet is suitable for all conventional tool clamping systems and as an additional bonus, the Schunk Tribos clamping device can be integrated as an option to enable Tribos tools to be length set, clamped and measured in seconds.

The TRISet allows users to significantly increase machine running times and reduce machine down time caused by tool setting.

Tools can be clamped, measured and adjusted outside the machine while the CNC machine continues to manufacture parts, delivering significant time savings.

* No axial displacement - the Tribos polygonal clamping technology is especially suitable for tool presetting.

In contrast to other toolholding systems, no axial displacement arises with the Tribos system as clamping occurs in the radial direction only.

The TRISet tool presetting system increases productivity in metal-cutting operations by 15% because the use of preset tools increases machine running times.

It also prevents reject components as even the first workpiece is machined to the exact size required with no deviation caused by the tool.

Moreover, said Schunk to manufacturingtalk.com, the TRISet offers the option of adjusting tools with exceptional precision using measurement programs for certain measurement tasks and checking the quality of the cutting edge.

Tool presetting enables micron precise tool measurement and this allows inspection of the cutting edge wear and edge quality.

The system also caters for measurement programs that monitor radial and axial run-out that determine the 'highest cutting edge' and 'largest diameter' dimensions.

* menu simplifies operation - the menu format simplifies operation considerably.

Length and diameter as well as cutting edge angle and cutting edge radius are detected within seconds thanks to ImageController1 image processing.

The setting devices are available in two measuring ranges with a measuring range of Z = 400mm and D = 400mm or a measuring range of Z = 600mm and D = 400mm.

To ensure quality over the long term, the Schunk Tribos presetting device depends on high-quality components, such as the Heidenhain measuring systems, THK guidance, Bosch pneumatics and computers from Sirius.

It is also important to highlight the tool mounting spindle with 4 x 90 deg indexing and 360 deg brake as well as the integrated calibration edge.

* Tribos polygonal clamping technology - the Tribos polygonal clamping technology was patented and developed by Schunk in 1997 and is based on a polygonal shape of the clamping bore.

In unclamped condition, it has a polygonal cross section.

If an exactly defined external force is applied to the clamping side of the toolholder, the clamping bore will deform.

The toolholder shank can now be introduced into a larger, circular bore.

After this force is removed, the clamping bore will return to its original shape and will clamp the tool shank.

Within seconds, the tool is changed using a hydraulic clamping device.

Minimize Toolchange Times

The Matrix Tool Magazine’s fourposition revolving disk keeps the next tool
ready and waiting for a machine’s toolchanger arm. This eliminates any delay, even after a short machining cycle.

Machine operators also can access a fully secure carousel-style rack to load tools without interrupting magazine operation. A high-speed servo-driven transfer robot then delivers tools to the work area.

As a stationary tool-storage rack, the Matrix allows shops to tool up their Toyoda (www.toyoda.com) horizontal machining centers for more part numbers, keep back-up tools on hand and eliminate time-consuming trips to the toolroom.

The system accommodates as many as 500 tools, and a compact version holds 184 tools. Maximum tool lengths handled are 21.6 in., maximum diameters are 9.84 in., and maximum tool weights are 59.4 lb.

Features that make the Matrix easy to use include PC-based software, tool identification and monitoring, and OP Supporter software. The magazine’s compact design houses an array of tools in a footprint about the same height as the machine tool itself.

PC-based software shows a layout of the entire Matrix magazine, with easy-to-use touch-screen navigation. A second touch on any tool displays detailed information and an image for that specific tool.

The magazine controller reads the part program to pre-select and display the needed tools. Continuous monitoring the magazine, loading station and revolver keeps track of every tool.

Toyoda’s OP Supporter software enhances tool management by providing a convenient overview of the magazine at the machine CNC. This confirms that the right subprograms and tools are ready for each job. Tool change speed is automatically adjusted according to weight for optimal cycle time.

Advanced laser cutting and forming of tube shown

Integrated tube processing systems enable users to improve labour productivity and component quality while simpler programming and fast production of prototype parts speeds product innovation

Investing in modern tube processing technology as a direct replacement for traditional multiple machine processes offers UK industry a proven cost-effective counter to competition from low labour cost countries, said BLM Group UK. Investment will be the theme of the BLM Group's stand at the UK's MACH 2008 machine tool exhibition where, for example, visitors will be able to take part in a multi-media experience that highlights the key aspects of the tube laser cutting and profiling process.

Overall, the emphasis will be on BLM Group's 50-plus years of experience in the design and manufacture of tube laser cutting, tube bending and tube end forming machines and systems.

Integrated tube processing systems improve labour productivity and component quality and, with their ease of programming and fast production of prototype parts, drive new product innovation, said BLM.

* All-electric CNC tube bending machine - a classic example of the Group's technology-driven approach is its E-Turn all-electric CNC tube bending machine.

It has been designed specifically for the bending of small to medium sized tubes, typically used for complex car and motorcycle components, hydraulic pipes and furniture.

Because the complete head can rotate through 180 deg, the E-Turn is capable of left- and right-hand bending in automatic cycle.

BLM told manufacturingtalk.com that this eliminates work-in-progress and optimises just-in-time operation, while the all-electric technology contributes a 20-50% productivity increase when compared with 'traditional' powered models of bending machine.

The E-Turn machine is available in four maximum tube OD (outside diameter) capacities (30mm, 35mm, 40mm and 52mm).

Complex components requiring radii of less than 1 x diameter can be produced using the 'bend boost' device, which can have its power modulated during the bending process to avoid unsightly stress marks on high value components.

Precise control of the E-Turn's 12-axis movements, courtesy of BLM's Visual Graphic Programming (VGP 3D) software, significantly reduces set-up times because all parameters are stored and can be re-called without further mechanical adjustment being necessary.

The electric axes automatically adjust position, which enhances accuracy and repeatability, and components are not only produced 'right first time', they are repeatable batch to batch without undue reliance on operator expertise.

Since all axis movements are set automatically, a job change-over can typically be completed within two to three minutes.

This multi-tool stack tube bender - up to eight different bend tools can be mounted at any one time - brings with it fewer bend tool changes and less downtime.

The VGP 3D software allows checking on-screen, providing a reliable guide to component cycle times and identifying any possible collision risk.

And because the PC-based control selects the correct parameters, the guesswork is taken out of tube bending and the most complex of tubular components can be completed in one cycle.

Developing A Safer Way To Machine Magnesium

Machining magnesium parts is risky business. The small chips and fine dust generated during cutting are highly flammable and pose a serious fire risk if not properly handled. These particles are commonly removed from the machine tool by means of a vacuum extraction system, in some cases using a hood mounted near the cutting tool to collect particles as soon as they are produced. Dry machining or use of minimum quantity lubrication (MQL) in conjunction with this extraction method allow chips to be recycled and can eliminate secondary part cleaning operations. However, auxiliary collection devices hamper both tool changes and machine high speed movements.

Guide To CNC Machines

CNC machines are used in a variety of industrial settings and in woodworking shops. Most are out of the price range for the individual user, but can be purchased used for about half the price. These machines increase speed and accuracy when doing large jobs or repetitive tasks.

How CNC Machines Work

CNC machines are used in a variety of industry, manufacturing processes and woodworking shops. CNC routers are used for drilling holes. Some machines have the capability of holding several tools. This allows them to perform more than one operation at a time. They save time and improve accuracy.

CNC stands for Computer Numerated Control. This technology was first seen in the 1970s. The machines need to be programmed and set up properly before operation. Once the initial set up is completed, they are fairly easy to operate and keep running.

In CNC routers, they can be programmed to drill holes in an automatic fashion. This is faster and more accurate over several pieces than in manual drilling. The results are more uniform. This method is very beneficial for larger jobs that require a lot of drilling. Manual drilling can become tiring and when the operator becomes tired, the results can become inconsistent.

Types of CNC Machines

A CNC lathe is a good piece of equipment for cutting wood. These come in models ranging from fifteen to forty horsepower. The amount of power you need depends on the amount of wood you will use with the lathe. The best models operate in several different modes, from completely manual to all CNC. This allows you to tailor the machine’s operation for each project.

A Bridgeport mill is the best in milling technology. Mills are used in many industries, both large and small shops. They are efficient and reliable. Bridgeport mills are built to last a lifetime. However, they are very expensive. The price is out of the range that most people can afford.

The CNC mill is a specialty piece of equipment. It uses computer programming and robotics for accurate operation. The results are more accurate than any person could ever achieve. For this reason, Bridgeport mills are often used in the airline industry. Once the specs are entered, the CNC decides which tools need to be used and automatically changes the tools as needed.

Engraving equipment is made to engrave a variety of materials including glass, stone, metal, wood, composites and many others. The machines mark and engrave with more accuracy than could ever be achieved by hand. Everything from large signs to small lettering can be done, depending on your needs.

Buying Used units

CNC equipment is very expensive and out of the price range of most people. Buying used CNC electronics is an affordable option for some people. You can save nearly 50% or more on some equipment. Be careful when buying used, you want to be sure the equipment is in good condition.

A better option is to look for refurbished equipment. These machines have been inspected at the factory. Any broken or damaged components are replaced. In many cases, the machine is painted and new decals are applied. It’s like getting a new machine for a significantly reduced price. Often, you will get a one year warranty with reconditioned equipment. This gives you time to be sure it is working properly and if not, you can get it fixed for free.

CNC Carving Overview

High tech cnc carving has taken school projects a long way from a hammer, chisel and a block of wood that wound up being a birdhouse for Mom. Today’s students are using CAD programs and cnc machines to make a carving that includes intricate design features. The experiences help give them a running start with the skills they will need for tomorrow’s job market. Cnc carving is the process of using a computerized machine carving away the unwanted material from a stock piece, leaving only the computer aided design piece. A computer numerical controlled machine can maintain extremely tight tolerances to produce pieces with a very high level of precision. They can carve virtually any material, including metal, wood, plastic and even ice.

Specialized computer software takes CAD designs and ‘tells’ the cnc machine to cut a specified amount of material from a stock piece with specialized cutting tools. The machine will make a series of precision cuts on multiple axes to yield the finished cnc carving. Virtually any object that can be designed with a CAD program can be carved with a cnc machine.

A cnc carving can be extremely intricate within extremely tight tolerances. Once the machine is set, hundreds and even thousands of identical pieces can be carved. Tolerances as tight as 0.005 inches are possible.

One of the advantages of a cnc wood carving is that when the CAD design is created, the cnc machine can be used to make one or many identical pieces. Students in many schools are learning to come up with an idea for the project and design it with a computer and a CAD program. The design is then controlled number of cuts made by the cnc machine to produce a perfectly carved piece. Elaborate desks, coffee tables and other projects are now being built in many schools with this technology and equipment. Students in schools are given projects as a means of teaching them the technology and the machine operating skills necessary to run this equipment.

Cnc carving skills are necessary for design and development work as well as actual production. These are the important skills these students are learning. They are developing the ideas, creating the designs and using specialized software to translate them into designs to be used by the cnc machines. The actual operation of the machine requires only a minimum of skill relating to properly loading the stock material and removing the finished pieces. These skills development prepare the students for a much different career than could have been imagined when schools taught students to build birdhouses with a hammer, saw and piece of wood.

CNC machine performs variable radius bending

Although the company made its name in tube manipulation, and is a successful business that has been part of Metalrax Group for the past 30 years, Toolspec's managing director, Dick Corking, says it is probably more accurately defined as 'a producer of welded assemblies'. An example of this approach is the tube components for LH and RH versions of a tractor cab grab handle that are being produced on the sixth tube bending machine to be supplied by BLM Group.

Because both conventional and variable radius bending can be combined in the same automatic cycle, the BLM Dynamic 2 is particularly suited to producing the complex components often to be found in the design and manufacture of, for example, furniture, air conditioning systems, motor vehicles and 'yellow goods', such as tractors, excavators and earthmoving equipment.

However, when manipulating tube for these demanding applications the bending process should, ideally, produce a consistently accurate result if, as is the case at Toolspec, each tube component is subsequently placed in a fixture and lugs, brackets, plates and similar items robot welded in place.

Since manual intervention to correct any misalignment that may have occurred during tube manipulation is not an option, there is no room for error, especially when the component in question is a grab handle that locates directly onto glass and cannot be adjusted to fit when delivered to the assembly line.

'The fact that we robot weld the grab handle assembly combined with the actual configuration of the tee-piece demands that we bend the tube within a 2mm envelope, which for tube work is a very tight tolerance,' said Corking.

'We got the initial order before we bought this latest BLM machine on the basis of our track record for this type of work, and I am delighted to report that, over the past 18 months, we have maintained a consistent high quality and order quantities for this particular assembly are expected to double in 2007.' Toolspec produces a wide range of bent tubular products, from brake pipe assemblies to safety cages for earthmoving equipment, and is a long-established user of BLM Group equipment.

The tractor cab grab handle order has been placed by a French OEM and it is not the first time that Toolspec, with the help of BLM's applications team, has replaced an overseas supplier.

'To succeed against stiff European competition demands investment in modern production equipment and the Dynamic 2 has risen to the challenge of a difficult component and a high standard of accuracy and repeatability,' said Corking.

'Although the component features a multiple-radius bend it looks as though it is a single, gentle radius.

Even so, BLM Group was the only supplier prepared to guarantee that its machine would do the job - in a cycle time of around 45 seconds - and an added bonus is that the after-sales support is very good.' The Dynamic 2, which can bend tube up to 42mm diameter, can be equipped with up to two sets of bend tooling for conventional bending with two different radii, or compound bending with little or no straight between the bends.

This, combined with the capability of producing variable radius bends and curves along the entire tube length, makes it a totally flexible tube manipulation system.

The Siemens 840Di CNC fitted as standard to the Dynamic 2 uses digital technology and the graphical interface can be personalised to user requirements.

VISI-Series - machining STRATEGIST

The Shop Floor Machining Solution machining STRATEGIST is a CAM system designed for high speed machining with built-in logic for use with solid carbide and carbide insert cutters. Developed by the people at Vero International in England, machining STRATEGIST is used in Mold, Tool and Die, Prototype and Pattern shops for generating cutter paths on complex geometry developed in disparate CAD systems such as VISI-Modeling, CATIA, Unigraphics, Pro/Engineer, SolidWorks, and Solid EDGE.

Mould cut using machining STRATEGIST

Most popular CAM systems that are used in today's mold shops weren't designed with High Speed Machining in mind. In order to take advantage of today's cutter and machine tool technology, machining STRATEGIST had to be and was designed completely from scratch. Released less than 6 years ago, it is the newest technology on the market today.

Using the latest software development tools, Vero people created a CAM system that generates efficient toolpaths very quickly, while still maintaining unparalleled ease of use. Strategist also takes advantage of multiple processors for more productive programming. But, the biggest advantage of machining STRATEGIST is in it's toolpath generation. Because it maintains a cut stock boundary, it knows exactly where to go to remove stock. It allows use of higher feedrates because toolpaths are created without any sharp corners so cutter deflection is maintained more constant. And all this allows your CNC machines to run faster and more productively with less wear and tear.

Advanced Rest Machining
Steep and shallow areas are machined in a single toolpath with different strategies - steep and shallow machining - for each. Crucially, rest machining can be calculated in areas where the final cutter is smaller than the curvature of the part.

Point ReductionAll machining passes operations now support enhanced point reduction and arc fitting. Arc fitting is enabled by default for those operations where it is likely to have the biggest benefit. In benchmarking, reductions of over 50% in NC file size have been observed.

Horizontal Finish Machining
Horizontal surface machining has been designed to use a flat-based cutter. This strategy will dramatically reduce the time it takes to finish machine the flat areas on a complex 3D mould, and in finish machining pockets in aerospace components.

Rest Roughing
The system will calculate the rest areas of a selected toolpath - areas left on the surface that have been insufficiently machined - generate a stockmodel with this information, and edit passes to it.

This is a good way to generate efficient toolpaths, reducing air-cutting and shortening the machining time.

Morph Machining
Each pass in a morphed "patch" - the toolpath prior to linking - echoes the shape of the one before, while suggesting the shape of the one after. Akin to machining with the flow of a surface but by creating a set of boundaries with control points, the operator can exercise tight control on how a toolpath flows as it is mapped onto the model.

It is now possible to access two advanced machining presets quickly and easily from the menu, consolidating pencil milling and constant surface stepover.

Parallel Pencil Milling PassesA set number of passes are offset from an active boundary or existing single line toolpath.

Tapered cutter support extends to carbide insert button cutters, predominantly used for roughing. To leave a tapered finish, it is critical to rough with taper to leave a material-on condition.

Use 5 axis CNC machining for precise work

5 axis cnc machines are used for a variety of purposes. Large scale machines can be used to mill automobile sized pieces, including models for wind tunnels or casting. Smaller 5 axis cnc machines are also available, and these can save time by reducing the amount of material repositioning needed for 3D products. In order to understand 5 axis units, it is necessary to take a brief look at 3 axis machining. A standard 3-axis machine operates in 3 linear axes of movement (x, y, z). These axes of movement tell the tool where to begin and stop each procedure, and could produce 3D engraving. But if you wanted to machine the sides of the project you would be forced to reposition the material.

In addition, 5 axis cnc adds two more axes of movement (a, b). These two axes allow the cutting tool to tilt so that the sides of the material can be machined. The result is e.g. a cnc router that can produce highly accurate 3D products quickly and efficiently.

CNC routers with five axis are ideal for accurate, high-speed trimming, cutting, and routing of wood, plastic parts, composites, clay, and metals. These routers come in many different sizes, ranging from garage sized machines designed for making aluminum molds to larger models designed for accurate cutting and trimming of large aircraft parts and other components. They are fully automated, and allow the operator to input just a few commands to produce many different pieces. These machines can also help to trim and finish large metal and plastic pieces with just a simple cnc software.

Who uses a 5 axis machine

Because a 5 axis machines typically takes up a great deal of space, it is highly unusual to see these machines in anything but the largest shops and manufacturing plants. The high cost of a 5 axis machine also makes it prohibitive for users on a smaller scale. The most typical users are companies which need to produce large, one piece products with shaping, carving, or finishing on all sides. Plastics plants, aerospace factories, automakers, and fabricators are just few examples of industries which use 5 axis cnc technology.

About CNC Machining

Computer numeric control (CNC) machining is a manufacturing process that automatically shapes or forms metals or other materials into highly precise parts. This is done through the manipulation of raw materials by machine operated cutting tools. Precision CNC machining systems are equipped with a computer consisting of one or more microprocessors and storage units. CNC machines utilize specialized software in conjunction with CAD/CAM software systems to instruct the tooling to execute the exact movements necessary to create the part. Precision CNC machining is a highly automated process that requires very little attention from workers. Operators only need to load materials and make any adjustments to the design parameters in order for a CNC machining operation to run unattended for a certain period of time. Precision machining is an efficient and quick way to precisely produce detailed parts.

CNC machining can consist of a number of detailed operations including grinding, turning and precision laser work. They are essentially modern milling machines and the range of available procedures is vast. The process more generally begins with the loading of a “raw” metal piece referred to as a billet. This piece of metal may have been cast, forged or rolled. It is then cut via laser or other device to create highly detailed work, as in the case of laser CNC machining. The milling done by a CNC machine requires little “finishing” to remove rough edges or blemishes, but some post production work may be required to meet safety regulations.

The majority of the operations of a CNC machine take place on what is called a lathe. This lathe performs any operations which require the rotation of the piece in order for the cutting or milling to take place. Parts like the lathe require frequent calibration to ensure accuracy of operation. The maintenance required to keep a CNC machine working does make it a more expensive operation than other types of metal forming, yet the accuracy of the final part is greater, and the range of services available is much wider. Since acute angles are virtually impossible to create using a standard forging or molding technique, CNC machining has become the preferred metal machining method for many industries.

It is important to know the parameters of a machine part that is needed when utilizing CNC machine work services. Many CNC machining service companies will create the design code based on specifications given them. Often the CNC machining systems are able to take an existing part and create code based on photo imaging programs. Some companies will take a CNC file and create the parts on their machines. Many shops are able to handle both continual and short-run orders. A few CNC operations can create a decent amount of waste material, so looking for a shop which has appropriate, up-to-date recycling methods is crucial to saving material and money in the long run.

Wire EDM Machines: An Overview

While there are many brands and models of Wire EDM machines available today, the three most prominent manufacturers are Elox, Japax, and Mitsubishi.While each of these companies manufacture similar products, there will always be some varying features such as the User-interface with the CNC controller, the numbers of wires, be it a 4-axis or 5-axis Wire EDM machine, type of electrical current (AC vs. DC), and the gauges of wires that can be used.

Another very big difference will be the size of the tank in which the manufacturing is accomplished.Some examples of specifications for one model from each of these companies are:Elox Fanuc Model M - (the Fanuc indicating the type of CNC controller that is a component of the Elox Wire EDM) has an X-axis path of 20”, a Y-axis path of 14”, and a Z-axis path of 10”Japax Wire EDM Model LDM-S - has a Y-axis path 13.8” and capable of machining a work piece with the measurements of 15.7” x 19.7” x 5.9” and a table that moves 7.9” x 13.8”Mitsubishi Wire EDM Model DWC 110 H-1 - has an X-axis of 12”, a Y-axis of 18”, and a Z-axis of 10”Each of these models only represents one of many different models offered by their respective manufacturer.

Variations will be observed from model to model with some differences including the distance that each axis wire can travel, the size of product that can be manufactured and the CNC controller.When selecting a wire EDM machine, one must take into consideration the product that will be manufactured, the degrees of tolerance and variances that are allowed, how detailed the cut will be, and not least importantly, the funds available for purchasing the wire EDM.While Elox, Japax and Mitsubishi are three prominent manufacturers of wire EDM machines, remember that there are also other manufactures of wire EDM machines.

Fagor automation offers CNC systems - Machine tools of Spain: European quality

Conversational 8055i TC/MC CNC's from FAGOR AUTOMATION

The most outstanding feature of FAGOR AUTOMATION's CNC systems is their operating friendliness, simple and intuitive, which gives them a competitive edge widely acknowledged by our customers. There are standard models with ISO and high level programming with the possibility of conversational programming that make them adaptable to both single-part work and long runs.

Conversational CNC's from FAGOR AUTOMATION (8055iTC/MC) may be adapted to the usual work method of a shop and have been designed to make intuitive programming easier for the operator; they have an interactive editor based on operations associated with each one of the processes that make up the machining of a part. The previous graphic simulation helps verify each operation and correct the data entered.

The system is programmed very easily. All the automatic operations have an interactive help, geometry defining area and other areas to set the machining conditions of the roughing and finishing stages with several editing levels or types of cycles with their own screen. This minimizes the preparation time; and any operator, without previous programming knowledge, can operate the CNC and carry out typical operations efficiently.

Its intelligent profile editor, similar to an integrated mini CAD, helps create profiles without the need for complex calculations by directly entering the values and parameters of the part, run a previous simulation and machine the part defined. If the part is too complicated, the preparation may be faster than when using an external CAD-CAM.

Telediagnosis and Setup Assistance On FAGOR AUTOMATION CNC's

FAGOR AUTOMATION has developed the Telediagnosis option to remotely control all the incidences that may occur on the machine.

Just connect the CNC with the PC of the Technical Department via the internet through a modem. This way, the technician, from his work table and at his own PC can remotely manipulate and observe the system status (CNC-drives-motors). This functionality may be used to detect PLC program errors, do a setup, or change parameters (CNC, motors mad drives), saving in travel expenses and labor of the technicians and minimizing machine down time by receiving assistance and error diagnosis immediately.

In order to facilitate the setup, it offers assistance such as the oscilloscope function and the circular geometry test.

The Oscilloscope function shows the response of the axes in time. With this feature, the signals may be seen directly at the CNC. (variables of regulation, path, feedback, etc.) without requiring external devices to check the status and facilitate the adjustments of the machine. The advantage of this feature is that the setup and the troubleshooting of incidences are faster and the diagnosis easier (even remotely) because the signals generated by the oscilloscope may be sent by fax or email.

The Circular Geometry Test may be used to cheek the behavior of the axes when doing a circle by enlarging the measuring errors of the axes. This function helps detect mechanical misadjustments and check the performance of the electronic equipment quickly while saving on additional devices.
