Abstract

See full text

A workpiece is machined by setting a frequency response band of a control system for a rotation drive motor or a feed drive motor so that tool abrasion is within a predetermined allowable range. The frequency response band may be adjusted by adjusting a proportional gain and an integral gain. With the workpiece machined by such a process, where the frequency response band maintains tool abrasion within the allowable range, machining quality and efficiency are improved.
