Since it is necessary to process the electrodes, it is a labor-intensive process and the processing fee is expensive. Further, even if the discharge electrode is precisely machined into such a specific shape, the electrode is consumed with time as the electric discharge machining progresses, resulting in an error in the finished product.

できなかった。There is a wire-cut electric discharge machine as another electric discharge machine that does not require machining of such a specific shape on the electrode, but this wire-cut electric discharge machine is limited to machining a two-dimensional shape of a workpiece. Has been done. Since the electric discharge position cannot be controlled in this wire-cut electric discharge machine, the work itself must be moved when moving the machined part of the work, and the device for holding or moving the work is required. Is complex and expensive. Further, in this way, since the conventional wire-cut electric discharge machine cannot control the discharge direction from the electrodes, for example, when chips or the like are accumulated at the location where the discharge reaches, the discharge is concentrated and is good. I couldn't process it.
