Abstract
Herein disclosed is an electric discharge machine, by which, after the machining operation of a workpiece by an electrode has reached a predetermined position, the machining operation is further accomplished while rocking the electrode in a plane generally normal to the feeding direction of the workpiece for the machining operation. The workpiece has its respective portion uniformly machined by effecting the machining operation accompanied by the rocking motions for a preset period, e.g., either for a predetermined time period or a predetermined number of the rocking motions so that the precision of the finishing operation can be improved.
