Abstract
In this research, micro-pin fabrication by scanning electrical discharge machining was carried out according to two machining processes. As the first process, the shape of a groove is fabricated by scanning electrical discharge machining under the conditions of minus of electrode polarity. As the second process, electrode polarity is made to change and a micro-pin is fabricated for this machining groove as a base level. This report describes the forming characteristic of the micro-pin by this method.
