Renishaw Introduces High Accuracy Scanning Solution for CMMs
March 2003 - Renishaw introduces its new SP80 scanning probe, which uses innovative Renscan(TM) technology to provide outstanding scanning performance, as well as highly flexible use of styli for maximum productivity. In tests at Renishaw, the SP80 has achieved sub-micron 2D and 3D scanning performance, using section scans as defined within the ISO 10360-4 international standard for acceptance and re-verification for CMMs used in scanning measuring mode. These figures are all the more remarkable since they are from unknown path scans, before any data filtering has been applied.*
The SP80 is a passive scanning probe with isolated optical metrology and digital readheads with 0.02mm resolution, providing exceptional performance even with long styli. The SP80 carries styli up to 500mm length and 500g weight - including star configurations - without the need for counterbalancing, therefore maintaining maximum working volume.
A repeatable kinematic stylus-changing mechanism enables rapid stylus changing for flexible inspection of complex parts. There is no need for probe re-qualification after each stylus change, and stylus arrangements can be optimized to ensure the best results for each feature to be measured.
Like all Renishaw scanning probes, SP80 is very robust. The kinematic stylus modules provide crash protection in the X-Y plane and a patented bump stop prevents damage to the probe in Z-axis crashes by redirecting the impact through the outer body.
The SP80's passive "no motor" design avoids unnecessary system complexity and heat, and offers accurate position sensing through the use of patented Renscan technology. Like other Renishaw scanning probes, the SP80 avoids stacked-axis errors through the use of "isolated optical metrology" transducers that measure the 3D motion of the stylus directly, rather than sensing displacement of each probe axis individually.

* The test details were: CMM specification E = 0.5 + L/1000 (ISO 10360-2), Renishaw UCC1 controller, unfiltered data, test duration 107 seconds, 50 mm stylus length. CMM users should note that ISO 10360-4 results are affected by the machine specification, controller performance and probe calibration method, as well as scanning probe design.
