PH20 PLUS 5-axis Touch Trigger System

PH20 5-Axis Measurement System

The new Renishaw PH20 PLUS is the next generation of PH20 5-Axis technology; the infinite positioning, 5-axis, touch-trigger probe head from Renishaw. PH20 PLUS has been designed to address the limitations associated with feature accessibility and maximum working length offered by the current PH20 system.

Renishaw's PH20 PLUS 5-axis probe system delivers high performance 5-axis touch trigger measurement at significant time savings compared to conventional 3-axis touch probe systems. 

Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM's 3 axes to measure quickly, PH20 PLUS 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 PLUS'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 time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems.

PH20 PLUS Infinite Positioning

PH20 PLUS'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 PLUS automatically aligns itself with the part co-ordinate system, avoiding stylus collisions and the requirement for accurate fixtures.

The PH20 PLUS head has two rotary axes (A and B) and is normally mounted on the CMM quill to create a 5-axis measuring system. The PH20 PLUS B-axis is mounted on the CMM quill and can rotate continuously in both directions. The A-axis, which is orthogonal to the B-axis, has ±115° of travel.

PH20 PLUS Probe Family

PH20 PLUS incorporates Renishaw's long established TP20 probe system into a revolutionary motorized head system to give unprecedented touch-trigger measurement capability. 

The new range of PE20 modules feature the respective kinematic mount compatible with the new mount on the PH20 PLUS head.  This new kinematic mount enables modules with more mass (and more length) to be carried which extends the maximum reach by 107 mm.

PE20 is based on the current EM1 and EM2 modules and feature a range of working lengths from 68 mm up to 250 mm, giving a total working length from the center of rotation of 300 mm (with a 50 mm stylus).

The PH20 PLUS probe head maintains full backwards compatibility with the current generation of PH20 systems.  It is built to run on the current generation of UCC T5 controllers and has the adaptor to maintain the use of the current TP20 family of modules with the same working lengths and parameters.  The current detachable modules provide crash protection and can be still be automatically changed using the TCR20 change rack.  Current users of PH20 systems will be able to upgrade to PH20 PLUS and utilize their existing modules.
