A method of numerically controlled profile grinding.

摘要

A method is described of numerically controlled grinding for forming a curved profile on a workpiece using a rotary grindstone (1) having an arc-shaped grinding periphery. The rotating grindstone is moved along the target profile (A-C-B) of the workpiece, keeping a constant attitude thereof as long as point contact of the arc-shaped periphery of the grindstone on the target profile is maintained. Immediately before this satisfaction ceases to be satisfied, the attitude of the grindstone is reset to satisfy the same condition. <IMAGE>
