摘要： 该文打破了传统上一直认为零相位差振动钻削不能断屑和这种情况下振动钻削效果不明显的错误观点.理论和试验证实了零相位差及其邻域内的振动钻削在一定条件下可以实现断屑,尤其特殊的是还可以实现局部断屑.而且在钻削铝等软质金属材料的小深孔时,1/2局部断屑的切屑处理效果最佳,从而为这类材料的小深孔钻削提供了新的切屑处理方法,同时也丰富了振动切削的理论.

Abstract: Up to the present, all published vibration drilling chip breaking theories considered that in zero-phase-difference axial vibration drilling, chip breaking was impossible. This point of view was found improper by our experiments.
From tho point of view of kinematics, axial cutting depth at each point of the major cutting edge remains unchanged during the cutting process under ordinary conditions; chips would not be broken. However, when some ductile metals, such as industrial aluminum, are vibration drilled with relatively large vibration amplitude, special chip breaking phenomena appear, which favours the drilling process very much. Proceeding from the changing angle characteristics of vibration drilling, this paper proposes the new chip breaking theory, and some experimental investigations have been made.
