Systems for assessing machine-tool performance, plus products to increase automation, improve process control and allow on-machine part verification, will feature on Renshaw’s stand at Mach 2010.

For visitors sourcing off-line measurement products, Renishaw will also be introducing its retrofit service for coordinate measuring machines (CMMs), including Modus, the company’s first metrology software.

There will also be a range of new motion control products, including a 1nm resolution incremental encoder and an absolute optical encoder for rotary and linear applications that is said to be capable of 10 atoms resolution at 220mph.

Renishaw will demonstrate touch probe systems that use its frequency hopping spread spectrum (FHSS) probe signal radio transmission technology to allow automated job set-up and in-process measurement on all sizes of CNC machine tools.

The ultra-compact RMP40 probe is especially suited to multi-axis and mill-turn applications, while its variant, the RLP40 touch probe, is designed for more hostile turning environments.

A transmission-only module RMP40M is also being introduced.

Measurement on multi-axis machine tools is enhanced with the introduction of the latest version of Renishaw’s Productivity+ suite of PC-based probing software.

A key improvement is a multi-axis option that allows more creativity and efficiency in machining processes, which supported by Renishaw’s Rengage 3D technology-based touch probes and ultra-compact radio probes, gives process engineers and machinists a wide choice of flexible process solutions.

Also being shown at Mach 2010 will be the successor to Renishaw’s QC10 ballbar system, which is used for the assessment of machine-tool positioning and servo control performance.

The QC20-W ballbar features a Renishaw-developed linear sensor and Bluetooth wireless technology, which also allows testing in three orthogonal planes through a single reference point.

A single hardware setup means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy.

Axiset Check-Up extends Renishaw’s range of machine-tool testing and calibration systems, with a 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.

Renishaw will also address the issues faced by manufacturers suffering from inspection bottlenecks that tie up staff and expensive machines while waiting for vital measurement results.

The company said that it offers cost-effective CMM retrofits for all budgets and applications, from touch-trigger probing and three-axis scanning, through to the latest Revo five-axis measurement system.

The company offers a ‘one-stop shop’ upgrade solution, from its Modus metrology software and universal CMM controller, through to sensors and machine calibration.

Resolute is a true absolute optical encoder system that has dirt immunity and a specification that is designed to enhance position feedback.

Renishaw said that visitors to Mach 2010 will see the encoder is capable of 27-bit resolution at 36,000rev/min, giving a resolution of 1nm at 100m/s for both linear encoder and angle encoder applications.

Absolute position is acquired immediately at system switch on, so the exact orientation of axis and motor commutation angle are known without the need for a reference (datum) return.

Visitors to Mach will also be able to see additions to the Tonic range of incremental optical linear and rotary encoders, including 1nm and 2nm resolutions, a dual-output encoder interface and compatibility with Renishaw’s Dual Signal Interface (DSI) for angle encoding.

Renishaw will be making further announcements to its schedule in the run-up to Mach 2010.


A world leader in engineering technologies, Renishaw’s core skills in measurement and precision machining serve sectors as diverse as dimensional metrology, spectroscopy, machine calibration, motion control, dentistry and surgical robotics.

Sensors for co-ordinate measuring machines (CMMs) are an industry standard, from basic touch-trigger probes through to automated stylus and probe changers, motorised indexing probe heads, and revolutionary five-axis measurement systems.

Machine probes for CNC machine tools allow automated tool setting, workpiece set-up, in-cycle gauging and part inspection. Products include laser tool setters, contact tool setters, tool breakage detectors, touch probes and high accuracy inspection probes.

For motion control, Renishaw supplies laser encoders, optical linear encoders, optical angle encoders, optical rotary encoders, magnetic rotary encoders, magnetic chip encoders and magnetic linear encoders.

To analyse the static and dynamic performance of position-critical motion systems, Renishaw’s laser interferometer and environmental compensation system offers a linear measurement accuracy of 0.5 ppm, readings of up to 50 kHz and a linear measurement speed of up to 4 m/s, with a linear resolution of 1nm.

Renishaw’s Raman spectroscopy products exploit the Raman effect to identify and characterise the chemistry and structure of materials. A diverse range of analytical applications include pharmaceutical, forensic science, nanotechnology, biomedical and semiconductors.
