The basic process parameters in grinding processes are the cutting speed v c, the feed velocity v f, the depth of cut a e, and the width of cut a p (see Fig. 1, see also Denkena and Tönshoff 2011 ). The cutting speed is in general equal to the circumferential speed of the grinding wheel. The feed velocity is oriented in feed direction.
