PH20 is another innovative measurement product from Renishaw that transforms coordinate measuring machine (CMM) performance. For the first time, 5-axis technology developed for the multi-award winning REVO® measurement system is available for touch-trigger applications on all sizes of CMM.

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 three‑fold improvement in throughput over conventional systems.

PH20’s infinite positioning capability guarantees optimal feature access, minimizing stylus changes. Five-axis simultaneous motion allows larger parts to be measured on the CMM by minimizing the space required around the part for head rotation.

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.

PH20 features and benefits
• Incorporates 5-axis measurement technology, minimizing CMM motion and the associated CMM dynamic errors.
• Infinite positioning and 5-axis motion reduces non‑productive transitions between features.
• Infinite positioning and 5-axis motion aid access to difficult features.
• Rapid calibration with all positions inferred means more time measuring.
• Maximum reach up to 200 mm with maintained effective working length.
• Standard M2 styli for convenience.

Hardware integration
• The UCC controller is fundamental to the PH20 system.
• The UCC controller features routines particular to 5-axis motion and head-touch measurement.
• MCUlite-2 is the multi-function hand control unit required for the system.
• PH20 can fit to any machine, either directly to the quill or via a shank using a range of mounting adaptors.
• The PH20 is compatible with the existing range of TP20 modules, excepting the extended force module.
• MCR20NI is the recommended rack for stylus changing, but it is possible to use an MCR20.
• No air supply is needed.

Software integration
• The Renishaw UCCserver™ software application will provide the interface for PH20 control.
• UCCserver is based on I++DME command protocol.
• PH20 is fully integrated with Renishaw’s MODUS™ application software.
