抄録

This paper describes a new method for micro-EDM drilling which utilizes the wear of an electrode rod. In this method, the polality of the electrode rod is positive, and the rotating electrode rod is fed into the block electrode at a feed rate of several tens times higher than the normal one. Since the circumferential region of the electrode rod wears at a much higher rate than the central region, the end of the electrode rod is sharpened in a few minutes. At the same time, a cone-like micro-hole with a sharp bottom shape is generated in the electrode block automatically. Other results obtained are as follows: 1) In order to obtain longer needle shape, the optimal feed speed is 60pm/s. 2) With the increase of the discharge energy, the needle-shape becomes longer and thinner. 3) The needle-shape becomes longer and thinner with increasing the rotation speed.
