This paper deals with the tool feed rate optimization for smoothening of cutting force in end milling of workpiece with corner and straight parts.There is a difference between the cutting force in a corner part cutting and that in a straight part cutting.The cause of this is due to the difference in the instantaneous depths of cut in both cuttings.The scheme of this study is to prevent the generation of excessive cutting force in the corner part machining by comparison with the straight part machining.By dividing the NC(Numerical Control) cutting path of the corner part and changing the tool feed rate in each division,the cutting force in the corner part has been controlled.Furthermore,the possibility of realization of a shortening in machining time has been examined.
