ABSTRACT:
A cutting feed starting position control device for machine tools is capable of automatically shifting a cutting feed starting position in the machine tool toward a work a distance corresponding to a variation in size of a tool such as a grinding wheel due to dressing or truing, and again returning the shifted cutting feed starting position to an original position when it is desired such as a replacement of wheels, thereby completely removing various kinds of difficulties in a numerical machine tool control due to the variation in size of tools.
