Renishaw PH20 5-Axis Motorized Probe Head Features:
Easy access to features at any angle
PH20’s infinite positioning capability guarantees optimal feature access, minimising stylus changes. 5-axis simultaneous motion allows larger parts to be measured on the CMM by minimising the space required around the part for head rotation. PH20 automatically aligns itself with the part coordinate system, avoiding stylus collisions and the requirement for accurate fixtures.
The unique ‘inferred calibration’ technique developed for PH20 determines the head orientation and probe position in a single operation, allowing subsequent measurement at any head angle. Further modules only require a few touches on the calibration sphere before use. (Enhanced metrology performance is available if needed by calibrating the probe tip at the feature orientation.) These dramatic time savings accumulate as the calibration process is repeated on a regular basis to comply with quality procedures or following a probe crash.
Integral industry standard TP20 probe
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.
Improved touch-trigger metrology performance
- Repeatability – improved when ‘head touch’ method is used
- Accuracy – improved by using feature based calibration and ‘head touches’
- Pre-travel variation – automatic compensation
- Module changing – automatic tip offset correction
