A Study on the Micro Tool Fabrication Technology employing ELID(Electrolytic In-process Dressing) Technique

전해 연속 드레싱을 이용한 마이크로 공구 제작 기술

With increasing the needs for micro and precision parts, micro machining technology using micro tools has been studied to fabricate a small part with high density such as electronics, optics, communications, and medicine industry more than before. Though these micro tools have developed rapidly, it is difficult to apply them to micro fabrication technologies, because of the inherent manufacturing. In this study, micro tools(wc) to produce micro structures and parts were manufactured by cylindrical grinding machine employing ELID(Electrolytic In-process Dressing) technique and good dimensional accuracy was achieved. Furthermore we researched the characteristics of machining on the micro drilling using micro drills and manufactured micro tools. Finally it is confirmed that manufactured micro tools can be used for micro machining.
