Optimization of Ball End Milling Feedrate considering Variation of Slopes in the CNC Machining of Sculptured Surfaces

자유곡면의 경사도에 따른 볼엔드밀링 이송속도의 최적화 연구

This study presents the analysis of ball end milling machinability and its application to the determination of the optimum feedrate in the CNC machining process of sculptured surface. The methods which estimate the cutting force system is approached experimentally. The estimation strategy, named technological processor, was applied to the machining process of sculptured surface for finding optimum variable feedrate. From the result of practical implementation for the test model, it is ascertain that the technological processor have brought the dispersion of force profiles. As compared with conventional imposing of cutting conditions, the machining time has reduced by more than 60%.
