【 摘 要 】

In this paper, the dynamics of multi-edge trepanning vibration drilling is considered as multi-edges cutting with regenerative mechanism of oscillations excitation. The equations of new surface formation, the equations of motion for a system with one degree of freedom, and the fractional-rational cutting law are used for the numerical simulation of the dynamics of the cutting process. It presents the results of modeling the variation in chip thickness and shape of the chips.
