    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.

    摘要： A machining-energy calculating unit accumulates a discharge current value for each discharge position to calculate a machining energy in a certain time period from the present time to the past time. An energy-distribution changing unit determines the presence or absence of imbalance in the energy by obtaining a machining energy distribution in an up-down direction of the machining gap based on the machining energy, and when there is imbalance, the energy-distribution changing unit produces a new open/close pattern in which a machining energy distribution that eliminates the imbalance. Power feeding is then performed based on the new open/close pattern.

    摘要： A discharge-generation control unit applies at least a preliminary-discharge voltage pulse and a main-discharge voltage pulse between a wire electrode and a work. A discharge-position determining unit determines a discharge position from results of measurement by a plurality of current measuring units. A machining-energy adjusting unit adjusts machining energy generated by the main-discharge voltage pulse based on a discharge position determined before applying the main-discharge voltage pulse, and reflects a result of the adjustment on the generation of an electric discharge by feeding the result to the discharge-generation control unit.

One parallel connection terminal of the switching element group is connected to a positive electrode terminal of a DC power source, and one parallel connection terminal of the switching element group is connected to a negative electrode terminal of the DC power source. Respective other parallel connection terminals of the switching element groups are connected via a reactor. A pulse voltage that appears at opposite ends of the reactor due to a cyclic on/off operation of the switching element groups is applied to a load through a coaxial cable and a matching circuit.
