Abstract

A grinding worm (20) is dressed with a dressing wheel (42), which is moved along the worm path (43) during rotation of the grinding worm (20). The grinding worm as well as the dressing wheel are coupled with rotary encoders (23, 41) and with a servomotor (22, 40) each. The rotation angle of the dressing wheel is coupled by a program with the rotation angle of the grinding worm within the NC control system. Thereby the grinding pattern may be shaped on the tooth flanks (51) of the ground workpiece (50) in such a manner that the ground toothed wheel has an optimum (smooth) running quality.
