A Machinability test on the cutting position in the ball-end milling of hemisphere

볼엔드밀 반구가공에서 가공 위치에 따른 절삭성 평가

In this paper, the test of machinability according to the cutting positions when the ball end milling of hemispheric workpiece is carried out to find the optimum cutting position of free form surface die. Tool runout, cutting force. and chip form are measured. The results show that the optimum cutting condition to get the constant feed per tooth is the inclined angle of 40 degree of workpiece.
