Abstract
Hitherto mechanical lever systems and cams were used to effect the necessary relative movements between the workpiece and the grinding disc. In order to attain a higher production rate at improved quality, it is proposed to use electronic means for shaping the profile of a tool. The generating profile is once or several times provided in a convex configuration on the grinding disc. The workpiece is shaped by respectively definable translatory, rotatory and angularly-dependent relative positions between the workpiece and the grinding disc.
