ABSTRACT:
A numerically controlled grinding machine provided with an angular type grinding wheel and a numerical controller for controlling the feed of grinding wheel based upon a control signal from a measuring head which measures the diameter of a cylindrical side of a workpiece. The grinding wheel is moved along an inclined path to grind the cylindrical side and a radially inner portion of the shoulder of the workpiece, simultaneously. In response to the control signal from the measuring head, the feeding of the grinding wheel is stopped. Then, the numerical controller detects the difference between a target position and a actual position of the grinding wheel along an axis of a work spindle. Further, the numerical controller compensates another target position to grind the radially outer portion of the shoulder for the difference. Thereafter, the grinding wheel is moved to the compensated target position so as to grind the radially outer portion of the shoulder.
