Encoders and calibrators highlighted at
Mach
As well as systems to improve machine tool and co-ordinate measuring machine productivity, encoder and calibration products will be highlighted at Mach 2006 at Birmingham's NEC in May 2006.
As well as systems to improve machine tool and co-ordinate measuring machine productivity, Renishaw will highlight its encoder and calibration products when it attends the Mach 2006 exhibition being held at Birmingham's NEC from 15th to 19th May 2006 Mach runs alongside the Drives and Controls show, the UK's only exhibition dedicated to drives, automation, motion control and power transmission, which also includes a programme of conferences and seminars, including conferences on communications and industrial safety

Program editor software extends CAD support
Active Editor Pro dramatically increases the number of users who can benefit from its simple programming style, by adding support for CAD models from a large variety of CAD formats.
Visitors to Drives and Controls interested in position feedback and calibration systems should also take time to visit Renishaw in hall five, stand 5572.
In addition to compact optical, laser interferometer and magnetic position feedback encoder systems to meet the requirements of industrial automation, other Renishaw products of interest to Mach and Drives and Control visitors will include Quickview motion analysis software.
This tool will be demonstrated with the ML10 laser interferometer measurement system for machine calibration.
The focus for encoder systems will be a robust high accuracy linear encoder, high-performance high-vacuum encoders and high resolution laser interferometer encoders.
The firm's micron, nanometre and picometre position feedback systems are for applications from laboratory and medical instruments, and semiconductor manufacturing equipment, to machine tools, metrology systems and massive aerospace assembly machines.

Probes improve aerospace component consistency
The Rolls-Royce engine component is made of Inconel, a material that has to be machined correctly the first time, as it doesn't lend itself to re-work.
Visitors to Mach 2006 and Drives and Controls will see three of Renishaw's technologies for precision positioning - optical, magnetic and laser interferometry - each suiting difficult applications.
The latest Signum encoder range provides high accuracy, resolution and repeatability with high speed, high operating temperatures, low cyclic error (typically less than +/-40nm) and In-Trac optical reference mark, which remains phased over the entire speed and temperature specification.
The system provides intelligent signal processing, ensuring reliability, while Signum software enables optimum set-up and real-time system diagnostics via a PC's USB port.
The Signum Relm high accuracy linear encoder comprises the SR readhead, Si interface and 20um Relm scale, which comes in defined lengths.
Initially available in Invar, which provides a low thermal expansion of 1.4um/m/C, the Relm scale is offered with a choice of In-Trac reference mark positions and dual optical limits.
Together with the robust 20um spars, this enables the Relm to provide accuracy to +/-1um and resolution to 20nm for precision motion requirements.
The Signum RESM angle encoder is a one-piece stainless steel ring with 20um scale marked directly on the periphery.
It features the In-Trac optical reference mark, which repeats, regardless of direction, at operational speeds of over 4500rev/min (52mm diameter) and up to 85C.
The PC-based Signum software provides calibration, set-up optimisation and real-time diagnostics.
The result is simplified installation of the encoder system and on-going system maintenance.
The Signum Si interface with USB connection includes real time signal monitoring, readhead pitch adjustment, calibration of the encoder reference mark and incremental signals, remote system monitoring, advanced error logging and system configuration analysis.
Miniature magnetic rotary encoders are available in component, modular and packaged shaft-style models.
The RM family of magnetic encoders provides up to 4096-count positioning resolution, accuracy to 0.3 degrees, and operating speeds to over 30,000rev/min.
Non-contact magnetic design eliminates seals, bearings and moving parts for lifetime reliability.
Standard models provide shock and vibration resistance, while optional sealed models allow application in harsh environments and even immersion.
Low cost, compact size and design simplicity enable use in a wide range of industries.
The RLE fibre optic laser interferometer encoders deliver interferometer-based nanometre positioning accuracy from a remote laser source - even to two axes.
Six detector head choices allow careful matching to a wide range of requirements, including capability for picometre-level resolutions.
Fibre-optic beam delivery reduces optical path complexity, saves space on miniature machines, and keeps laser heat from affecting measurement axes.
Bolt down and dial in laser alignment enables ease of installation comparable with traditional tape- or glass-based encoders.
Applications include x-y stages, fibre-optic alignment machines, glass grinding machines, photomask machines and other precision motion systems.
An optional real-time compensation system enables positional accuracy of 1ppm (1um/m) in various environmental conditions.
The ML10 laser interferometer measurement system is used by some of the world's largest OEMs and end users in industries such as metal cutting, semiconductor processing, flat panel display production and biotechnology.
Linear position reading resolution is 1.24nm, range of up to 40m and accuracy better than 1ppm.
This combination of resolution, accuracy and range makes the laser interferometer suitable for characterising the performance of motion systems, large and small.
Quickview can make the ML10 a more flexible and powerful analysis tool.
It provides mechanical engineers with a capability to study minute variations in linear or angular displacement, velocity or acceleration.
With a simple graphical interface, Quickview allows flexible operation, avoiding the need for predefined measurement targets and sequences - just point and measure, suitable for ad-hoc system investigations. Request free introductory details about products from Renishaw ...
