Abstract
Electrically operated apparatus for adjusting the working position of a machine tool to compensate for such conditions as tool wear by automatically maintaining a predetermined position of the tool within desired tolerance limits. In response to a signal from automatic gaging equipment indicating the necessity of moving the cutting tool either toward or away from the workpiece, a synchronous electrical motor drives tool compensating apparatus to provide for adjusted movement of the tool through a predetermined incremental distance. Limit switches determine the working and retracted positions of the tool and a movable slip ring which carries the limit switch actuator enables movement of the tool to adjusted working positions to compensate for tool wear.
