Cusp 패턴 조정과 미소 볼엔드 밀링을 이용한 3차원 자유곡면의 다듬질

Abstract

The ball-end milling process is widely used in the die/mold industries, and it is very suitable for the machining of free-form surfaces. However, cusps(or scallops) remaining at the machined part along the cutter paths require another finish process such as polishing or grinding. In this study, a high speed micro ball-end milling method has been suggested for the finish of free-form surfaces. A new tool path which makes the geometrical roughness of workplace be constant through the machined surface has been developed. In the high speed machining of micro ball-end mulling experiments, the developed tool paths have been successfully applied. And it was concluded that the surface roughness from this finish cuts of micro ball-end milling process was acceptable.
