【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。更多还原

【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.更多还原
