Abstract
In a wire electrode discharge machining method the breaking of the wire electrode is positively detected by detecting a discharge signal between the wire electrode and the workpiece over a predetermined unit period of time, and then monitoring the average value of high frequency components included in the spectrum of the discharge signal which are independent of the vibration of the wire electrode. When the average value of the high frequency components is found to exceed a predetermined level, countermeasures are taken to avoid the breaking of the wire electrode.
