볼 엔드밀의 경사면 가공에서 공구경로와 절삭속도에 따른 공구수명의 특성
Characteristics of Tool Life according to the Cutting Direction and Cutting Speed in Machining on Inclined Plane using Ball End Mill
초록
This paper deals with the establishment of the cutting direction on inclined plane by using ball end mill. Ball-end milling is widely used for free form surface die and mold. In these machining, the cutting parts vary because the tool tip is hemisphere shaped. The cutting characteristics, such as cutting force, surface roughness and surface profile are varied according to the variation of cutting directions. The effective tool diameter was calculated on different tilt angles and tool-path. Tool life and cutting characteristics were estimated on variation of cutting directions in the same cutting speed. In this paper, the optimal cutting direction which can be applied 3-D sculpture surface cutting is suggested.
