REVO 5-axis measurement system
Multi-sensor 5-axis measurement system
The REVO system uses synchronised motion and 5-axis measurement technology to minimise the dynamic effects of CMM motion at ultra high measurement speeds.
This is achieved by letting the REVO-2 head do the fast demanding motion while the CMM moves in a linear slow fashion. The use of a flexible tip-sensing probe further adds to the system’s accuracy and performance. The removable probe system, used in conjunction with a low cost changer, provides added system flexibility.
The 5-axis measurement technology is embedded in Renishaw’s UCC S5 CMM controller which forms the basis of the 5-axis measurement system – 3 machine axes plus the 2 rotary axes of the head. Patented technology within the UCC S5 provides unique motion commands, synchronisation 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 UCC S5 and SPA3 system.
REVO system change rack
The REVO system change rack is designed to allow automatic 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 (RCP TC-2, RCP TC-3 and RCP2) and a flexible change rack (FCR25). These ports are mounted on the modular rack system (MRS2).
Calibration on traditional CMM systems consumes a considerable amount of time that could otherwise be used for part measurement. Using a table mounted sphere, the simple and practical calibration technique for REVO-2 determines the actual head and probe geometry, allowing measurement in any position from a single operation.
Where a CMM is used only for a single or limited number of parts, typically there may be 10 head orientations used. Calibration time for these positions may take around 30 minutes. REVO-2 requires only 20 minutes.
If the CMM is used for multiple parts, typically there may be 40 head orientations, dramatically increasing the time required for calibration to around two hours. Again, REVO-2 requires only 20 minutes.
As the calibration process is repeated on a regular basis, to comply with quality procedures or following a probe crash, these time savings accumulate.
