<p>A workpiece registration unit provides dimension signals representative of the diameter of a cylindrical workpiece while a plunge cut therein is made by a grinding wheel of a grinding machine. The dimension signals are provided in response to a workpiece error signal generated by a gage having probes in contact with the workpiece. During the plunge cut, the dimension signals are utilized to control movement of a wheel slide of the grinding machine which is connected to the grinding wheel. The movement causes a responsive change in wheel slide signals provided by a wheel slide registration unit. After substantially completing the plunge cut, the wheel slide signals are altered to correspond to the dimension signals of the workpiece registration unit. The probes are retracted from the workpiece and a portion thereof having a keyway therein is plunge cut with the (previously) altered wheel slide signals being utilized to control the movement.</p> |
