| Outline of Final Research Achievements |
Peeling tool, which consists of a thin wire (core) coated with a low melting point metal (clad), has been proposed as a microelectrode in micro-EDM. In this study, we tried simultaneous machining of micro-hole drilling and clad removal of "peeling tool" with 10-micrometer core. The surface roughness of the peeling tool was less than 2 μm and eccentricity of the core was around 2 μm. Micro-hole drilling and removal of the clad were carried out simultaneously with copper plate of 50-micrometer thick. After the drilling, shape of the hole drilled consisted from two parts; circular dent slightly larger than clad diameter and a small through hole at the center of the dent. The core of few tens of micrometers, which was a tool for drilling the hole, appeared after the first drilling. Then through hole without a dent was obtained for consecutive 3 trials using this revealed core. On-the-machine tool forming and consecutive micro-hole drilling were demonstrated.
