PURPOSE:To enable to effect a correct and highly accurate feeding for an auxiliary working by a method wherein an electric discharge machining upon the feeding for the auxiliary working is effected by a revolutional working process including an eccentric circular motion which is easy to control. CONSTITUTION:A method of working in the present invention includes a revolutional working process wherein an electrode 10 is fed for an auxiliary working by an eccentric circular motion along X-Y plane and a vector working process wherein the electrode 10 is fed for the auxiliary working along a predetermined vector. The eccentric circular motion is shown by a notation 200 while the vector feedings are shown by notations a, b, c in the diagram. The revolutional working process has many advantages as follows: it is consisted of the eccentric circular motion, therefore, control of the feeding of the electrode 10 for the auxiliary working is very easy; most of the necessary electric discharge machining can be effected in this revolutional working process; consumption of the electrode 10 in this occasion can be highly uniformed; and the like. |
