Method for profile machining

Abstract:

A method for profile machining comprises: providing an electrode having an electrode axis, a free axial end with an end face, and a peripheral surface other than the end face; energizing the electrode and a workpiece having a thickness, with one of the workpiece and the electrode as an anode and the other as a cathode; and machining the workpiece with the peripheral surface of the electrode, during which the peripheral surface and the electrode axis of the electrode are across the workpiece in a thickness direction thereof. In addition, an embodiment of present invention relates to a component machined by the method.
