For solving troubles happened during the drilling process with carbon fiber epoxy composite materials(CFRP) by using HSS drill, a few types of diamond gift electroplated drills are manufactured, and machinability of these drills is experimented with a variety of cutting speed and feed rate. These drills have some advantages of good wear resistant and the conception of grinding process. As a result, using of these drills improves both troubles being caused by tool wear and damage of exit surface depending on fiber stacking angle. It is desirable that cutting conditions for the cutting thickness per revolution must be set under 0.01mm when the size of a diamond grit is # 60 .approx. 80.

산업현장에서 많이 쓰이는 절삭설비(Metal Working : MW)는 매우 다양하여 일일이 열거하기는 어렵고 주로 자동차생산업종, 농기구제조업종, 각종 기계기구 생산업종, 경금속가공업종 등에서 매우 광범위하게 사용되고 있다. 이들 업종에서 연마, 절단, 천공, 드릴링, 터닝(turning)등을 수행하는 많은 근로자들이 다량의 MWF(Metal Working Fluids) 뿐만 아니라 열악한 소음환경에 노출되고 있다. (중략)
