System description

RTP20 is an indexable head that uses the CMM's motion for repeatable repositioning.  It offers low­cost 'motorised' head functionality with
an integral TP20 touch-trigger probe.
Automated indexing of the head is realised through an innovative process which uses the motion of a CMM to achieve motorised head style
operation. This indexing process comprises of three operations:
An external locking lever on the probe head is driven against a dedicated sphere mounted to a pole located on the bed of the CMM, thus
unlocking the head
The CMM motion is then used to engage a drive-cup located in the head's A-axis swivel, with the pole-mounted sphere, enabling rotation
of the head in the A and B-axes by driving around the pole
The indexing operation is completed by again using the CMM motion to drive the locking lever against the pole-mounted sphere, thus
locking the head
The automated indexing of the RTP20 allows the integral TP20 probe to be moved to 168 repeatable positions in 15-degree increments
using both the A and B-axes, requiring a one-time only qualification for each stylus position thus ensuring fast throughput for part
inspection. Using the CMM motion to lock and orientate the head together with the MCR20 change rack, which allows repeatable
interchange between qualified probe modules, provides a fully automated system.
NOTE: The red LED on the front of the head indicates probe status, and can be controlled by either the CMM or a Renishaw probe
interface. Conventionally LED ON indicates probe seated (armed), and LED OFF indicates probe triggered.
Electrical connection is via a 5 pin DIN connector.
