ABSTRACT:
A numerical control grinding machine, in which rough grinding and finish grinding wheels are used to machine a workpiece into a predetermined shape. A sensor detects the finish grinding wheel contacting the workpiece surface when shifting from the rough grinding to finish grinding operations and determines its position. The numerical controller of the grinding machine calculates the difference between actual and theoretical sizes of the workpiece and completion of the rough grinding operation based on the finish grinding wheel position. After that, the controller compensates the rough grinding wheel position in the next machining cycle for the difference calculated by the controller.
