Measurement probe RFP1

non-contact

The REVO fringe probe (RFP1) is a non-contact structured light sensor for the REVO® system offering highly accurate measurement of surface topology on an infinite positioning, 5-axis CMM platform. RFP1 increases the multi-sensor capability of the REVO system, which now offers interchangeable tactile scanning, touch-trigger, surface finish, non-contact structured light and vision probes. The RFP1 probe is designed for inspection of free-form surfaces and complex geometry, rapidly delivering patches of surface data with a high point density. The probe projects a fringe pattern onto the part surface, capturing variations in the fringe pattern with the camera to build a point cloud of 3D surface data. Automatic exposure controls compensate for different surface materials, colours and textures, ensuring optimal data results without the need for matt coatings. Unlike other non-contact structured light systems, the RFP1 fringe probe does not require reference markers to stitch together data from different patches – this is done automatically by the REVO system. Two new software tools provide easy-to-use inspection planning and digitising. The RFP inspection planner is a tool for path planning and generating DMIS part programs from CAD, whilst the RFP digitiser collects data from parts without CAD models as part of a reverse engineering process.
