摘要：
There is disclosed a method for electrical discharge machining of a workpiece in the form of a roll by application of an electrical voltage across said workpiece and an electrode or electrodes mounted opposite to each other with a predetermined gap therebetween, and more particularly such method wherein each such electrode is formed by plural electrode segments separated from one another by insulators, and the electrical discharge operation is performed with said electrode segments in each electrode short-circuited to one another in the rough machining step and with said electrode segments insulated from one another in the finish machining step for reducing the working time.
