Abstract
A method and apparatus for electric discharge machining the front and rear surfaces of a workpiece having thin-walled parts by using electrodes, in which the front and rear surfaces of a workpiece are discharge machined simultaneously by securing a workpiece in position on a movably adapted table, supporting two electrodes having surfaces corresponding to the front and rear surfaces being machined of the workpiece in such a manner as to face the surfaces being machined of the workpiece in such a manner and as to be retractable with respect to the surfaces being machined of the workpiece, and controlling the two electrodes so that the two electrodes are brought close to the workpiece in synchronism with each other at substantially the same traveling rate per unit time.
