Graphic display method of machining state in numerical control grinding machine
First Claim
1. A method for graphically displaying a machining state in a numerical control grinding machine which effects both inner surface grinding and outer surface grinding and which includes a display device having an image display for displaying images of a cylindrical workpiece being subjected to machining as well as working surfaces thereof, said method comprising displaying an image of the workpiece on the image display as a projection thereof on a plane parallel to an axis of the workpiece, and changing at least one of a gradation, hue and tone of each machining portion of the image of the workpiece throughout in a direction normal to the axis of the workpiece in accordance with changes in a grinding state of each machining portion, storing a plurality of different display gradations, display hues or display tones, and dividing a total grinding amount in a plurality of grinding cycles into parts displayed in a plurality of different display gradations, display hues or display tones, the displayed gradation, hue or tone being changed in accordance with changes in the grinding state, and when the workpiece is being subjected to inner surface machining by the numerical control grinding machine, displaying the workpiece and the working surface thereof as a projection of a section through the workpiece which includes the axis of the workpiece projected on a plane parallel to said section.

Abstract
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.
