At the IMTEX exhibition taking place in Bangalore, India, from 20th to 26th January 2011, Renishaw will highlight a range of process control solutions that help tackle the increasing drive to lean manufacturing, from new technologies for pre-process machine calibration, to on-line and off-line post-process measurement.
New pre-process calibration tools include the QC20-W wireless ballbar, as well as Renishaw's latest advancement in fast 5-axis CMM measurement – the motorised PH20 probe head with "head touch" capability. Rounding out the exhibit will be the company's CMM retrofit service, encoder technologies and demonstrations of software for calibration, machine tool probing and CMMs. Major highlights include:
QC20-W wireless ballbar
In addition to the conveniences of wireless operation, the new QC20-W ballbar is the first calibration tool to allow testing in 3 orthogonal planes through a single reference point. A single, simple hardware set up means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy.
Fast, automated health check for multi-axis machine tools
AxiSet™ Check-Up extends Renishaw’s market leading range of machine tool testing and calibration systems, with a new cost-effective solution for checking the alignment and positioning performance of rotary axes. In just a few minutes, users of five-axis machining centres and multi-tasking mill-turn machines can now identify and report on poor machine alignments and geometry that can cause extended process setting times, as well as non-conforming parts.
PH20 5-axis probe for CMMs
The PH20 increases touch-trigger CMM throughput up to three times, using fast, infinite, rotary positioning and unique "head touch" capability for high-speed point capture with minimal CMM movement. The PH20 uses two-axes of head motion to minimise CMM movement and associated dynamic errors at higher measurement speeds. Its unique "inferred calibration" feature determines head orientation and probe position in a single operation, eliminating the need for calibration at each orientation.
New machine tool probes with optical and radio signal transmission
Renishaw's new RLP40 and OLP40 lathe inspection probes offer a choice of signal transmission technologies – radio or optical – to make part set-up and inspection on turning centres accurate, simple and reliable. Measuring just 40 mm (1.57 in) in diameter and 58.3 mm (2.30 in) long, the probes provide unidirectional repeatability of 1µm (0.00004") and can be used to reduce set-up times, scrap, and fixture costs, while improving process control.
CMM retrofits and software
Renishaw will detail its certified coordinate measuring machine (CMM) retrofits to upgrade existing machines to state-of-the-art capabilities – including REVO™ five-axis ultra-high-speed scanning. The comprehensive retrofit program applies to all brands of machines. The Renishaw Retrofit™ service enables manufacturers to raise CMM throughput by factors of four, five and more, increase measurement automation, collect more data points for form measurement, and utilise open source software and future probing technology developments.
New multi-axis software for machine tool probes
New OMV Pro software includes more advanced CMM-type capabilities with an extended range of geometric dimensioning and tolerancing (GD&T) functionality, plus the ability to work with multiple alignments in a single program, an advantage in working with multi-axis machine tools. The software includes simulation capability, an intuitive graphical interface and crystal-clear reporting format that make it accessible to shop-floor staff. OMV Pro's GD&T measurement wizard helps users create standardised report elements based on internationally recognised symbols, allowing operators to compare part measurement results on the machine with those on the manufacturing drawing.
Absolute optical encoder and 1 nm resolution incremental encoder
RESOLUTE™ is the world’s first true absolute encoder capable of 27 bit resolution at 36,000 rpm. The fine-pitch system offers excellent dirt immunity, while delivering market-leading resolution of just 1 nanometer at up to 100 m/s, for both linear and angle encoding applications.
TONiC™ incremental optical encoders provide the accuracy of fragile fine-pitch encoders, but in a rugged, simple-to-install package. Advanced optical design and innovative electronics are featured in a compact readhead (35 mm x 13.5 mm x 10 mm L-W-H) for great design/application flexibility and installation even on micro-manufacturing systems. New additions to the TONiC range of linear and rotary encoders include 1 nm and 2 nm resolutions, a dual output encoder interface, and compatibility with Renishaw’s Dual Signal Interface (DSi) for high accuracy angle encoding.
