초록

본 연구에서는 수직 밀링에서 탄소섬유 에폭시 복합재료를 절삭할 경우 절삭 조건에 따른 공구마멸 형태를 조사하였으며, 여유면 마멸량을 측정하여 Taylor 지수를 구하였다. 또한 절삭조건 및 측정 방향에 따른 표면거칠기를 조사하여 탄소섬유 에 폭시 복합재료의 가공특성을 조사하였다.

Carbon fiber epoxy composite materials are widely used in the structures of aircrafts, robots and other machines because of their high specific stiffness, high specific strength and damping. In order for the composite materials to be used in the robot structure or machine element, bearing mounting and joining surfaces must be provided, which require accurate machining. In this paper, the machinability and tool wear characteristics of the milling operation of the carbon fiber epoxy composite materials were experimentally measured. The tool wear mechanism and the Taylor tool wear constants were determined. Also, the surface roughness of milling operation was measured w.r.t. cutting speed and feed.
