Probe Heads
PH10 PLUS motorized indexing heads
The range of PH10 PLUS motorized probe heads increases throughput by giving automated CMMs the added capability of program controlled probe re-orientation. This enables the inspection of features at different angles without the need for frequent, time consuming stylus cluster changes.
About the PH10
The range comprises three PH10 PLUS models, each of which can carry a range of probes and extensions and can be orientated in 720 repeatable positions, giving access to the most difficult-to-reach workpiece features.
All three variants of the new PH10 PLUS heads are now supplied with a revised repeatability specification, down from 0.5 µm (2σ) to just 0.4 µm (2σ) (specified at a distance of 62 mm), giving users improved positioning at the stylus tip. The new specification heads are physically differentiated by a new ‘aqua blast' finish which gives a modern, matt black appearance.
The PH10M PLUS can carry long extension bars and complex probes such as SP25M or TP7M. The highly repeatable autojoint allows rapid probe or extension bar changing without the need for re-qualification.
The PH10MQ PLUS is a variant of the PH10M PLUS that allows the motorised head to be attached directly to the quill with the B-axis of the head inside the quill itself. This option provides a neater and shorter probe mount, with only the A-axis protruding from the quill.
The PH10T PLUS is similar to the PH10M PLUS, except that it features an M8 thread probe mount in place of the autojoint. All M8 threaded probes, such as TP20 and TP200, and extension bars fit directly onto the head. The PH10T PLUS is fully compatible with all of Renishaw's stylus and module change systems.
PH20 5-axis touch system
PH20 is another innovative measurement product from Renishaw that transforms co-ordinate measuring machine (CMM) performance. For the first time, 5-axis technology developed for the multi-award winning REVO® measurement system is available for touch-trigger applications on all sizes of CMM.
Improved touch-trigger metrology performance
Repeatability – improved when ‘head touch’ method is used
Accuracy – improved by using feature based calibration and ‘head touches’
Pre-travel variation – automatic compensation
Module changing – automatic tip offset correction
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.
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.
REVO2® five-axis measurement system.
REVO is the first in a range of revolutionary products to offer 5-axis measurement capability and is designed to maximize CMM throughput whilst maintaining high system accuracy.
About Revo
Multi-award winning multi-sensor system
REVO is a dynamic measuring head and probe system from Renishaw. A revolutionary product designed to maximize CMM throughput whilst maintaining high system accuracy.
In recognition to the revolutionary 5-axis measuring technology that has brought dramatic benefits to part inspection on CMMs, REVO has received three international technology awards:
Queen's Award for Enterprise 2013
Most Innovative Product Platinum Award at ENGIMACH 2010
Innovation Micron d'or Award at Micronora 2008
Best quality control product or system winner at the MWP 2008
REVO uses synchronised motion and Renscan5™ measurement technology to minimise the dynamic effects of CMM motion at ultra high measurement speeds.
This is achieved by letting the REVO head do the fast demanding motion while the CMM moves in a linear slow fashion. The use of a flexible tip sensing probe system further adds to the system's accuracy and flexibility. The removable probe system, used in conjunction with a low cost changer, provides added system flexibility.
The Renscan5 technology is embedded in Renishaw's UCCS5 CMM controller which forms the basis of the 5-axis measurement system — 2 of these axes are rotary and at the CMM quill. Patented software capability within the UCCS5 provides unique motion commands, synchronization and 5-axis metrology capability.
In order to achieve the high scanning speeds it is essential the 5-axis measurement system has a fully integrated control loop. This is achieved using Renishaw's UCCS5 and SPA3-2 system.
REVO changer system
The REVO probe change system is designed to allow automatic REVO probe and stylus holder changing on a CMM. The primary purpose of the system is to improve flexibility with the ability to use and store longer styli and large star stylus configurations.
For optimum metrology, REVO probes and stylus holders should be changed automatically using REVO change ports (RCPTC and RCP) and a flexible change rack (FCR25). These ports are mounted on the modular rack system (MRS).
Faster calibration
Calibration on traditional CMM systems consumes a considerable amount of time that could otherwise be used for part measurement. The unique calibration technique developed for REVO determines the actual head and probe geometry, allowing measurement in any position from a single operation, thus dramatically reducing calibration time.
