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.

Increase CNC machine tool productivity

CAD/CAM developer and metrology specialist are to hold two free seminars in the UK on increasing machine tool productivity

CAD/CAM developer Delcam and metrology specialist Renishaw are to hold two free seminars on increasing machine tool productivity in the UK during March. The first event will be at Renishaw's Wotton-under-Edge base on Tuesday March 4; the second will be at Delcam's Birmingham headquarters on Thursday March 6.

Both events will show delegates the many ways in which Renishaw's hardware and Delcam's software can help companies to increase the productivity of their machine tools.

The presentations will be divided into three sections.

1 - Ways to prepare for maximum machining efficiency - these will include the use of the latest calibration methods from Renishaw to check machine tool set-up and advanced programming strategies from Delcam to give more efficient machining.

2 - Faster and more accurate methods to set up jobs on the machine and to maintain efficient process control - these techniques ensure that the machine is not only manufacturing parts more quickly but also that the parts being made are of the required quality.

3 - Latest inspection techniques, especially on-machine verification - these techniques ensure that any problems can be identified as soon as possible, allowing them to be corrected more quickly and at lower cost.

'Many companies have invested heavily in very capable machine tools but find that they are not achieving the productivity gains that they expected,' said Renishaw's Marc Saunders.

'These seminars will show delegates practical measures to improve machine tool efficiency and so increase profitability.'
