초미립 WC로 제작된 무코팅 엔드밀 공구의 가공성 평가
Machinability evaluation of non-coated end mill tool fabricated by ultra-fine WC
초록
The quality of tool material is very important factor in machining evaluation. The characteristics of tungsten carbide, such as grain size and hardness, and density are depending on the variation of Co composition and WC size. In this study, the non-coated end mill which is made of ultra-fine tungsten carbide is investigated by measuring tool wear and tool lift test. The machining test is conducted with high hardened workpiece under high-speed cutting condition.
