ABSTRACT:
A traveling wire electric discharge machining apparatus machines a workpiece by applying periodic voltage pulses to a wire electrode while moving the wire electrode relative to the workpiece. A location on the workpiece is determined, according to a predetermined parameter. The location is before a change in machining direction of the workpiece. When the wire electrode is positioned at the determined location, a characteristic of the periodic voltage pulse is changed.
