【Abstract】 To improve the safety and efficiency of milling process, it is necessary to predict the physical features such as milling forces and vibration parameters, etc. before actual cutting.A geometrical model of the ball end mill is presented.A method combining theoretical cutting force analysis with experimental identification of milling force coefficients is used to develop the milling force model. The measured data and simulation data under various cutting conditions are compared and show good consistency. It is proved that off-line simulation can give accurate prediction of ball end milling forces.更多还原
