摘　　要：通过振动钻削实验装置,采用普通麻花钻和螺旋面钻头在不同的振动钻削参数下对高温合金和碳钢进行振动钻削实验,分析基于螺旋面钻头普通钻削和轴向振动钻削条件下不同的断屑效果.并针对钻削中轴向钻削力和扭矩进行实验研究和理论分析,研究普通麻花钻和刃磨螺旋面麻花钻对加工过程的不同影响.实验结果表明:与普通钻削所得的切屑比较,振动钻削有利于断屑,切屑体积小,排屑顺畅;复杂螺旋面振动钻削中轴向力与扭矩比普通麻花钻小,其轴向力的变化过程也比普通麻花钻平稳.With the aid of the vibration drilling table,experiments were carried out on high temperature alloy and carbon steel under different parameters by using normal twist drill and helical drill,respectively.The differences of breaking chip effect between the vibration cutting and the normal drilling of helical drill were studied.The axial drilling force and the torque of vibration drilling were experimentally and theoretically studied.Effects of the use of normal twist drill and helical drill on the machining process were theoretically discussed.The results showed that,compared to ordinary drilling,vibration drilling is favorable for chip breaking,small chip and easy chip removal.The vibration drilling force and torque by using the complex helical drill are much smaller than that by normal twist drill and the change of the drilling force is relatively steady.
