Even small machines need accurate measurement. The PH20 probe head increases CMM inspection throughput up to three times because of its fast, infinite, rotary positioning and its unique “head touch” capability for high-speed point capture. Designed for use with the industry-standard TP20 touch-trigger probe, the new PH20 head brings 5-axis inspection capability to smaller CMMs.
Conventional touch-trigger measurement relies on speeding up the movement of the CMM’s 3 axes to measure quickly. The PH20, however, uses head motion to minimize CMM movement. The probe head saves time with synchronized motion of the head and CMM between measurements. Its rapid “inferred calibration” technique determines head orientation and probe position in one operation, allowing subsequent measurements at any head angle. It also enhances inspection efficiency with adaptive positioning to accommodate part misalignment.
It incorporates the TP20 touch-trigger probe, for access to a range of proven probe modules and trigger forces, directional sensing options, and extensions. Current users of TP20 systems can upgrade to the PH20 and use all existing modules, with the exception of the extended-force module.
The PH20 system uses a Renishaw UCC controller, which connects to existing metrology and application software through the I++ protocol. As a retrofit package, the PH20 comes with the controller and Renishaw’s MODUS™ metrology software for a fully integrated solution. It is available for new CMMs, as well as retrofit machines using shank or quill mounting. It can use most existing inspection programs for indexing heads without modification, and requires no compressed air.
