Zusammenfassung:A method for electrical discharge machining a workpiece includes the steps of: presenting an elongate electrode to the workpiece with a spark gap therebetween; flowing a dielectric fluid in the gap; eroding the workpiece by electrical discharge between the tip of the electrode and the workpiece; displacing the electrode in a direction aligned with the long axis of the electrode to maintain the gap as the electrode wears and the workpiece is eroded; and simultaneously with the displacement, producing vibratory movement of the electrode, the vibratory movement being aligned with the long axis of the electrode. 种用于放电加工工件的方法,包括以下步骤:将长形电极提供给工件,其间具有电火花间隙;使电介质流体在间隙中流动;通过电极的末梢与工件之间的放电来腐蚀工件;当电极磨损且腐蚀工件时,使电极沿与电极的长轴线对准的方向位移来保持间隙;以及在位移的同时,产生电极的振动移动,振动移动与电极的长轴线对准。
