Machining Time Reduction in Rough Machining of Sculptured Surface using Filleted End Mill

필렛 엔드밀을 이용한 자유곡면 황삭가공 시간단축

The cusp height in ball end milling, flat end milling and filleted end milling according to various surface inclination angle was calculated. The calculation result shows that, for each kind of tools, there exists certain range of inclination angle in which cusp height characteristics favorable. From machining time calculation, filleted end mill found to be superior to flat end mill in rough machining of sculptured surface.
