3D profile generation by dot-matrix EDM (1st report) -proposal of dot-matrix EDM-

摘要

This paper deals with a new prototyping method called a dot-matrix method by electrical discharge machining (EDM). In this method, shapes are machined on a workpiece by scanning bundled wire electrodes. The machining process by the dot-matrix method is similar to the printing process with a dot-matrix impact printer. A prototype of a machining unit has six miniaturized electrode feeding devices. It measures 55 x 55 x 80mm. wire electrodes of 0.3 mm in diameter are arranged with the pitches of 0.72mm.
