Touch-Trigger System – 5-Axis

Renishaw Metrology Systems 5-axis, touch-trigger system, 5-axis, Model – PH20. PH20’s unique ‘head touches’ allow measurement points to be taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster, and with improved accuracy and repeatability. Furthermore, 5-axis motion eliminates time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems. Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM's 3 axes to measure quickly, PH20 utilises the head motion technology developed for the multi-award winning REVO® system to minimise the dynamic errors of the CMM at higher measurement speeds. Intelligent head technology affords rapid touch-trigger measurement by using 'head-touches' where measurement points are taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster, and with improved accuracy and repeatability. Highlights include easy access to features at any angle and faster calibration. Users of the PH20 probe head will immediately have access to the range of proven TP20 probe modules, providing a wide selection of trigger forces, directional sensing options and extensions to meet application requirements. The detachable modules provide crash protection and can be automatically changed using the MCR20 change rack.
