We propose a new electrical-discharge machining method, in which an isolated bundled electrode is used for a high removal rate without deteriorating the surface finish. This phenomenon is due to the formation of small multicraters by a single pulse, even in a high-energy discharge. The effects of the discharge conditions on crater shape in a single discharge and on surface roughness in multiple discharges were experimentally investigated. The experimental analysis clarified that the use of isolated bundled fine-wire electrodes results in superior surface roughness compared with the use of a solid electrode.
