Renishaw plc New Mills, Wotton-under-Edge, Gloucestershire, GL12 8JR United Kingdom RTP20 compact probe head RTP20 offers low-cost ‘motorised’ head functionality with integral TP20 touch-trigger probe The RTP20 is a compact probe head with DCC capability and integral TP20 touch-trigger probe. The RTP20 probe head allows the integral TP20 probe to be moved to 168 repeatable positions in 15-degree increments using both A and B axes, requiring a onetime only qualification for each stylus tip position. This eliminates the need for costly time consuming requalification routines, ensuring fast throughput for part inspection. Automated indexing of the RTP20 probe head is realised through an innovative process which uses the motion of a CMM to achieve ‘motorised’ head style operation. This indexing process comprises three operations as follows: • 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 polemounted sphere, enabling rotation of the head in the A and B axes, by driving around the pole. Both axes can be re-orientated using the same unlock operation, increasing the efficiency of the operation. Once the head is in position, the drive-cup is disengaged from the sphere. RTP20 integral TP20 probe mount optimises the working volume of the CMM and provides compatibility with all existing TP20 modules. Although modules can be changed manually, the RTP20 can be used with the MCR20 module change rack, allowing fully automated module changing. RTP20 can be installed on new and existing measuring • The indexing operation is completed by again using the CMM motion to operate the locking lever against the pole-mounted sphere, thus locking the head. The head is now ready to measure a feature. machines via a shank mounting, involving just the initial qualification of each measuring position and stylus combination. The new probe head is fully supported by all standard CMM controllers, including Renishaw’s UCC controller family. Productivity Improved productivity is achieved via probe module changing and automated indexing without the need for constant re-qualification. Automation Utilising the CMM motion to lock, unlock and orientate the head, together with the MCR20, provides a fully automated system. Increased reach and flexibility A built-in extension together with existing extension bars allow reach up to 168 mm (including maximum stylus length). Crash protection TP20 modules have overtravel in all directions. The magnetic mounting provides additional crash protect
