Surface Finishing Probe Accurately Evaluates Workpiece Surface Finish/Roughness

Verisurf Software Inc. announces a surface finish probing and reporting solution for CNC coordinate measuring machines (CMMs) equipped with Renishaw Revo SFP2 (surface finish probe).

The surface finish probing feature is included in the soon-to-be-released Verisurf 2024, a measurement, reverse engineering and inspection software built on a full-featured 3D CAD/CAM platform with intelligent model-based definition (MBD). Using direct output from the Renishaw REVO SFP2 probe, Verisurf CMM programming can include defined surface finish/roughness evaluation from 6.3 μm to 0.05 μm Ra with results added to automated quality reporting. This is made possible by Verisurf support for Renishaw Revo multi-sensor five-axis probing. Surface finish measurement is fully integrated with the standard Verisurf CMM inspection program and includes automatic changing of probes, based on the inspection plan, which eliminates CMM downtime and maximizes inspection throughput.

The REVO SFP2 works on a variety of surfaces including bores as small as 5 mm (0.196") using a 2, 5, or 10-micron radius diamond stylus tip, and can output Ra, RMS and raw data for further analysis and reporting. When combined with Verisurf the solution is said to provide detailed and accurate data that can be verified against a nominal 3D CAD model, enabling operators to make informed decisions regarding component quality and acceptability.

Verisurf operates Renishaw equipped CNC CMMs through the Verisurf Device Interface (VDI), which supports two-way communications with virtually all sensor types and brands. The VDI sends programmed instructions to operate the CMM and collects measurement data for analysis and processing.

“Depending on the application, many customers can reduce or eliminate the need for dedicated optical and stylus profilometers,” Nick Merrell, executive vice president of Verisurf Software Inc., adds.
