Abstract

Standard gear measuring systems (e. g. coordinate measuring machines) are conditionally suitable for extensive large gear measurements due to individually limited measuring volumes. Therefore, an opti-cal scalable multi-distance sensor system consisting of a confocal chromatic sensor in combination with a rotary table is presented and referenced with a tactile measurement. The determined standard deviation of the profile slope deviation of a small spur gear amounts 1.23 μm. Further, with a suitable calibration strategy, simulations show that uncertainties of less than 1 μm can be achieved.
