Five-Axis Head for Touch-Trigger Inspection on CMMs

Utilizing technology developed for its Revo measurement system, Renishaw says its PH20 probe head offers “head touches” for rapid touch-trigger measurement and fast, infinite, five-axis positioning for optimal feature access. Its compact design makes it suitable for new CMM purchases as well as a retrofit for existing CMM touch-trigger installations.

CMM users are said to benefit from the probe’s adaptive positioning, which is designed to accommodate part misalignment and fast calibration routines. An integral TP20 probe mount optimizes the working volume of the CMM, bringing five-axis capability to smaller machines, the company says.

By incorporating the industry standard TP20 touch-trigger probe, users of the PH20 probe head have access to a range of probe modules, providing a selection of trigger forces, directional-sensing options and extensions to meet application requirements. The detachable modules provide crash protection and can be changed automatically using the MCR20 change rack. Companies with existing TP20 systems can to upgrade to PH20 and utilize their existing modules.

The PH20 probe head saves time with a rapid “inferred calibration” technique that determines head orientation and probe position in a single operation. This enables subsequent measurement at virtually any head angle. The system’s design requires no air supply, and it can be mounted to the CMM quill either directly or via a shank using a range of mounting adaptors.
