摘要:
An electric discharge machining apparatus includes a wire electrode for machining a workpiece, and a first voltage applying unit for applying a voltage pulse. The voltage pulse has a rise time longer than a discharge formative time lag when a rectangular voltage pulse is applied, when a distance between the workpiece and the wire is an average value in machining, and rises to the same voltage as the rectangular voltage pulse.
