Renishaw PH20 - PH20 system description; Calibration

PH20systemdescription
PH20 is a dynamic measuring head and probe system from Renishaw. It is a revolutionary product designed to
maximise measurement throughput whilst maintaining high system accuracy for basic entry level measurement
systems.
PH20 incorporates Renishaw’s long established TP20 probe system into a revolutionary motorised head
system to give unprecedented touch trigger measurement capability. Unlike conventional touch trigger
measurement methods which rely on speeding up the motion of the CMM’s 3 axes to measure quickly PH20
uses head motion to minimise the dynamic errors of the CMM at ultra high measurement speeds.
PH20keyfeatures:
 Infinite positioning – not restricted to defined index angles
 Rapid head touches – where the CMM is stationary and the head moves and takes a touch point
 Rapid 5 axis moves – synchronised motion of the head and CMM between measurements
Calibration
PH20 uses a standard Ø25 mm datum sphere, available from Renishaw under part number A-1034-0026.
