ABSTRACT:
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.
