The arcuate surface Wa is machined by cutting toward the arcuate surface Wa along a moving path S that is offset by a certain distance e. In order to obtain high machining accuracy, the feeding of the grinding wheel G is carried out by numerical control, and the current position of the grinding wheel G is displayed to make it easier to confirm and adjust the position of the grinding wheel G at the cutting forward end. That's what I do.

とが困難な問題があつた。 However, since the conventional device simply displays the amount of movement of the grindstone G along the movement path S, it has been difficult to confirm the finished diameter of the arcuate surface Wa. That is, when the moving path S of the grinding wheel G is offset, the change in the diameter of the arcuate surface Wa is not proportional to the change in the amount of movement of the grinding wheel G, and the position along the moving path S of the grinding wheel G is not proportional to the change in the moving amount of the grinding wheel G. For those that display the arc surface while looking at the position display.
There was a problem in which it was difficult to check and adjust the finished diameter of Wa.
