PRt¢I Performance verification of three-axis CMMs The UK National Physical Laboratory is running a one day course on the performance verification of three-axis coordinate measuring machines (CMMs), at Teddington, UK, on 16 June 1988. The course is aimed at technical managers and technicians who use CMMs. Particular emphasis will be given to the recently published British Standard on CMMs, BS 6808. The topics covered will include: the verification of CMM performance using the principles set out in BS 6808; the role of step gauges in the verification procedure and step gauge calibration; the importance of good software for coordinate metrology; and the part played by the National Measurement Accreditation Service (NAMAS) in this field of measurement. The role of CMMs in Advanced Manufacturing Technology (AMT) will be discussed and the
findings of a recent NPL survey will be presented. During the course there will be an opportunity to see NPL's work in the field of standards for coordinate metrology, to discuss calibration problems with staff, and to see BS 6808"s implementation demonstrated on a CMM. The fee for the course is £150 + VAT and covers lunch and refreshments, notes on the topics discussed and a summary of the survey entitled "CMMs in AMT'. Places are limited.

Optical profile projector The vertical lens axis projector from Sigma, the VF600, allows measurement to 2.5/~m. It uses a
Hardware version of contouring control system A hardware version of its own TNC 155 contouring control, with a separate keyboard and logic unit, is available from Heidenhain. The keyboard unit of the fouraxis contouring control TNC 355, is 3 cm deep and weighs 1.6 kg and therefore allows easy installation into fixed or swivel type machine Operating panels. For the logic unit, installation into the switching cabinet is recommended, this simplifies wiring for connection of the linear encoders. At the same time, better temperature control for the electronic components is provided. The screen with graphics facility has not been changed with
vertical light beam to project the image of a component supported on a flat glass workstage, onto a large screen 600 mm diameter, allowing the component to be measured. Among the features of the optical profile projector included in the system is the provision of an add-on computer system and comprehensive software package to provide extensive additional geometric function facilities. Linear measurement options range from micrometers to electronic systems with edge detection and geometric function facilities. An electronic angular measuring system is offered as standard. A comfortable operator viewing position is maintained, and all the company's standard measurement systems are sited at an ideal viewing height. The silo-type turret mount affords maximum projection-lens projections, and highly flexible fibreoptics are used for surface illumination.

the exception of the connector for the connection cables. The system is suitable for connection of linear encoders with distance-coded reference marks which enable determination of absolute position value after max 20 mm traverse, Programmable functions include: drilling and milling cycles, cycles for coordinate conversion, parameter programming, shopfloor and external programming, and graphics machining simulation via the screen.
