Measurements on pinion type gear shaping cutter using coordinate measuring machine

A pinion type gear shaping cutter is used to cut both external and internal gears following the generating principle. The cutter has a complex geometry and its inspection poses a number of problems. A Coordinate Measuring Machine (CMM) can be conveniently used to inspect the pinion type cutter. The theoretical basis of the measurements on a pinion type cutter is presented in this paper. Typical results of the measurements obtained using a CMM are also included.
