摘要：基于轴向振动辅助钻削原理，探讨了振动钻削对切出进给方向毛刺的影响。结果表明：由于施加轴向振动的作用，钻削加工中出现了脉冲和变厚钻削的过程，改善了钻削过程中的切屑的断屑条件，降低了轴向钻削力，从而减小了切削层材料的塑性变形，抑制了切出进给方向毛刺。

Abstract:Based on the fundamental theory of axial vibration drilling，the influence of vibrationdrilling on the feedexit burr is analyzed.The result shows that，due to axial vibration，vibration drilling has some unique characteristics，such as variablethickness cutting and impulse cutting，which not only improve the chipbreaking conditions and working angle of the drill，but also reduce the thrust force.Therefore，the plastic deformation of workpiece material and theexit burr are effectively restrained and decreased.
