Zusammenfassung:	PROBLEM TO BE SOLVED: To improve machining efficiency by omitting unnecessary zero cutting.SOLUTION: A machining method uses: an AE (acoustic emission) sensor 6 for detecting vibrations when machining is carried out; and a controller 4 for controlling machining by a machine tool 2. The machining method includes a removal machining step and a zero cutting step. In the machining method, a threshold is set, which is a value lower than those of the vibrations detected by the AE sensor 6 when removal machining is carried out. When a detection signal from the AE sensor 6 is lower than the threshold when the zero cutting is carried out, the zero cutting is ended.
