RFP Fringe Probe Increases Flexibility of 5-Axis System

Renishaw Inc. outlines the advantages of its RFP fringe probe, designed for use with the REVO five-axis measurement system on coordinate measuring machines (CMMs).

The RFP probe increases the multi-sensor capability of the REVO system by adding non-contact structured light inspection to the existing product range, which now offers five different probe families, each specifically designed to maximize the advantages of five-axis motion and infinite positioning. All REVO system probes can be changed automatically and include tactile scanning, touch-trigger, surface finish, non-contact structured light and vision probes. They are all used within a common coordinate reference frame, providing the choice of an optimum tool to measure multiple features all on a single CMM platform.

The RFP projects a fringe pattern onto the part surface and the probe’s camera captures the variation in fringe pattern to build a point cloud of 3D surface data. The data cloud is then evaluated by the 3D metrology software to deliver the inspection results. Non-contact structured light inspection with the RFP delivers clear advantages over traditional tactile probing techniques for freeform surfaces and complex geometry, such as additively manufactured parts, aerospace blades and blisks, automotive cylinder head combustion chambers, and delicate surfaces not suited to tactile measurement.
