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.
