Abstract: The vibration model of ball end milling process considering the effect of cutter flexibility is presented．The influence of the axial force on the inherence frequency of the cutter is studied．Considering the feedback of dynamic deflection of the cutter and vibration mark on the milled surface on the transient chip thickness，model of dynamic milling process is developed．Furthermore，corresponding simulations are made．It is shown that offline simulation could give predictions to dynamic features of milling process．
