Abstract: 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.
