PH20

For more than 40 years, Renishaw has delivered innovations that have been milestones in industrial metrology. From the original touch-trigger probe and motorized indexing head, repeatable stylus changing and modular scanning systems, Renishaw sensors for coordinate measuring machines (CMMs) are an industry standard.

PH20 5-axis touch-trigger system:

PH20’s unique ‘head touches’ allow measurement points to be taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster and with improved accuracy and repeatability. Furthermore, 5-axis motion eliminates time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems.

Unlike conventional touch-trigger measurement methods, which rely on speeding up the motion of the CMM’s 3 axes to measure quickly, PH20 utilises the head motion technology developed for the multi-award winning REVO® system to minimise the dynamic errors of the CMM at higher measurement speeds.

Intelligent head technology affords rapid touch-trigger measurement by using ‘head-touches’ where measurement points are taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster and with improved accuracy and repeatability.

Easy access to features at any angle:

PH20’s infinite positioning capability guarantees optimal feature access, minimizing stylus changes.

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.

Faster calibration:

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.
