Abstract
An apparatus includes one wire electrode wound multiple times around a plurality of guide rollers to form a parallel wire part in which a plurality of wire cutting parts are arranged in parallel, a discharge waveform control device that controls an interpolar voltage waveform based on a discharge waveform command, and a wire running control device that controls running of the wire electrode based on a wire electrode running command. Further, there is a cutting stage drive device that controls a relative position between the parallel wire part and the workpiece based on a stage command, a machining state acquisition section that acquires a cutting part electrical characteristic or electrode state information as machining state information, and a machining control device that determines the wire electrode running command, the discharge waveform command, and the stage command based on the machining state information.
