ABSTRACT:
A multiple-axis milling-, sculpturing- or shaving-type EDM machine removes material from a selected surface portion of a workpiece with a continuous traveling-wire electrode guided at an end portion of a tool head and juxtaposed with the workpiece. The wire is continuously advanced and transported from a supply reel to a takeup reel on the tool head by drive means to continuously renew the active electrode surface at the guide section while a position controller moves the tool head in a scanning manner relatively over the workpiece surface. A high-frequency mechanical vibration is imparted directly or indirectly to the wire electrode carried by the guide section while traveling in juxtaposition with the workpiece.
