PH20 5-axis touch-trigger system
It’s infinitely better.
Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM’s 3 axes to measure quickly, PH20 utilizes the head motion technology developed for the multi-award winning REVO system to minimize the dynamic errors of the CMM at higher measurement speeds.
PH20’s unique ‘head touches’ allow measurement points to be taken by moving only the head, rather than the CMM structure. Points can be taken faster, and with improved accuracy and repeatability.
Furthermore, 5-axis motion eliminates the time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems.
Easy access to features at any angle
PH20’s infinite positioning capability guarantees optimal feature access, minimizing stylus changes. The 5-axis simultaneous motion allows larger parts to be measured on the CMM by minimizing 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 angle. Further modules only require a few touches on the calibration sphere before use (enhancing 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 TCR20 change rack.
