摘要： To provide an electric discharge device capable of performing an optimum process that achieves a high-quality process in a satisfactory quality of processing precision and the like. In an electric discharge device that processes a workpiece by electric discharge, a reserve electric-discharge pulse is applied by alternately switching between a positive polarity and a reverse polarity, and a current waveform shape of a main electric-discharge pulse is differentiated corresponding to a polarity of a reserve electric-discharge pulse, to a main electric-discharge pulse to be applied after detecting electric discharge following the reserve electric-discharge pulse. With this arrangement, a processing current shape can be optimized corresponding to an electric discharge characteristic, and thus a high-precision process can be performed.
