On a display device, one or more machining portions in the entire working surface of a workpiece are displayed as image variations in gradiation, hue or tone throughout in a direction normal to the axis of the workpiece, to thus facilitate recognition of the machining state. A graphic display system is combined with a numerical control grinding machine to display images of a workpiece being machined and its working surfaces. The workpiece is displayed on the display device as a projection thereof on a plane parallel to the axis of the workpiece. Machining portions in the entire working surface of the workpiece are displayed in gradation, hue or tone changes, throughout in a direction normal to the axis of the workpiece, in accordance with changes in the cut-away amount. |
