In a method for successively generating, on the inner peripheral surface of a ring, the individual profiles of a plurality of teeth of an internally toothed gear wheel: positioning the ring on a turntable; imparting complex motions, at a predetermined speed relationship therebetween, on the turntable; rotating a contoured grinding wheel, via both axial and radial feeding motions, as the grinding wheel enters into the inside of the ring for the tooth profile generation; keeping the tip radius of the grinding wheel at least substantially similar to the radius of the arc shape of each tooth; and continuously maintaining but a single contact line, between the grinding wheel and the ring inner peripheral surface, during the actual generation of the tooth profiles on the inner peripheral surface of the ring, with the complex motions including both, at least partially concurrent, angular and orbital movements, in the same angular direction.
