Abstract
In an electric discharge machining apparatus for machining a workpiece by confronting an electrode and the workpiece through an insulating machining solution, feeding the electrode to the workpiece and causing electric discharge between the confronting electrode and workpiece the difference between the most advanced position of the electrode relative to the workpiece and the present position of the electrode is detected and a signal is outputted by identifying the interelectrode state in accordance with the detected result. Thus, the propriety of the interelectrode machining gap state in the electric discharge machining are accurately observed, and the workpiece is machined under preferable machining conditions.
