Precise Geometrical Inspection

Measurement technology from Micro-Epsilon is being used to inspect machines manufactured by engineering company EHR from Pforzheim. EHR’s precision machines are used for the inspection of hypoid-toothed gearbox components or cutting tools for crankshafts. A movable laser scanner from Micro-Epsilon is mounted centrally on the measurement set-up. Unlike conventional tool presetters, not only can external areas be scanned from this position but also the internal profiles of measurement objects. The laser scanner has a resolution of up to 1µm and was adapted to suit the measurement accuracy and cycle time requirements of the customer.

Therefore, 3D point clouds are obtained from the relevant part areas, which provide enough data for application-specific evaluation. This is a major benefit when compared to tactile measurements, which provide only a few measuring points in a relatively long measurement period. As well as the scanCONTROL 2800 laser scanner, optoNCDT laser sensors and optoNCDT 2401 confocal sensors are also used on this test station.
