Renishaw will show its latest range of motion control products at Automation Technology Expo West (ATX) 2010, which is scheduled to take place in Anaheim, California, on 9-11 February.

The company will exhibit a true absolute optical encoder for rotary and linear applications, a track-mounted linear-encoder scale system and a magnetic encoder chip.

Also on show will be the new QC20-W wireless ball bar, which assesses machine-tool positioning and servo-control performance and now includes a volumetric testing capability, and a range of new touch probes and probe software that increase machine-tool automation and improve process control.

For visitors sourcing offline measurement products, there will also be the opportunity to discuss Renishaw’s new retrofit service for coordinate measuring machines (CMMs), including Modus, the company’s first metrology software.

Resolute is a true absolute optical-encoder system that has excellent dirt immunity, according to the company.

Visitors to ATX 2010 will see that it gives 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.

Large setup tolerances also facilitate installation, while low jitter and sub-divisional error meet the demands of high-precision stages.

Fastrack is a track-mounted linear-encoder scale system that combines +/-5um/m accuracy, with the ruggedness of stainless steel and the quick installation of a carrier-type encoder system.

Designed for applications that demand high accuracy and removable scale, ATX visitors will see that the Fastrack scale system consists of two miniature guide rails that securely retain Renishaw’s new low-profile scales and allow them to freely expand at their own thermal-expansion coefficient with almost zero hysteresis.

If damaged, the scale can be pulled out of the guide rails and quickly replaced, even where access is limited, thus reducing machine downtime.

Renishaw’s new AM4096 magnetic encoder IC, developed by associate company RLS, provides UVW outputs with 16 poles (eight pole pairs) and incremental, absolute, linear (potentiometer), tacho-generator and sinusoidal outputs.

Resolution is to 12-bit (4,096 steps per turn) with a programmable zero position and it is capable of high-speed operation to 30,000rev/min.

Typical applications for the new on-chip magnetic encoder include commutation and high-speed motor control, position and velocity control, potentiometer replacement and optical-encoder replacement.

The ATX show includes robotics, control software, motors, drives and motion control systems.

It is located in the Convention Center in Anaheim and is co-located with complementary shows such as Medical Design and Manufacturing West, Plastec West, Electronics West and the Pacific Design and Manufacturing Show.

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.
