An electric discharge machining method which is practiced with stable machining condition and with high machining efficiency. The condition which, in machining a workpiece, tends to place the gap between the electrode and workpiece in unstable state is detected, and the period of time for which the condition thus selected lasts is set so that the discharge energy of a pulse voltage applied across the electrode and the workpiece is reduced for the period of time thus set. Therefore, in the electric discharge machining method of the invention, the machining operation is maintained stable with high machining efficiency at all times.

Electric discharge machining method

In a wire electrode supplying device, a contact detector detects when a wire electrode supplied through a wire guide is brought into contact with the upper surface of a workpice, to output a detection signal, and in response to the detection signal, a control unit operates to suspend the supplying of the wire electrode and to insert it into a machining start hole formed in the workpiece while binding it with a jet stream, whereby the wire electrode is positively inserted into the machining start hole even when the wire guide is remote from the workpiece.

Wire electrode supplying device in wire cut electric discharge machine

A mechanism for preventing the loosening of a wire electrode of an EDM apparatus which is wound around a bobbin. The mechanism is provided with a loosening preventive device 5 including a presser plate 8 for pressing the outer periphery of the wire electrode against the bobbin by a spring pressure. The loosening preventive device presses the wire before electrical discharge and is separated from the bobbin when the electrical discharge is started. When the wire is broken or the wire feeding is stopped, the wire breaking or the feeding stop is detected and the presser plate is immediately pressed against the outer periphery of the wire so as to prevent the returning wire from bulging or backlashing out of the bobbin.
