ABSTRACT
Vibration tapping is conducted under the action of impulse force through the logistic movement of the tap that is controlled by servo motor. The vibration tapping experiments of the titanium alloy TC4 are conducted with M6 down chip hard alloy taps. The effect of the rotation angle ratio, the forward rotational speed, and the reverse rotating speed on tapping torque is studied by the experiments. The results indicate that vibration tapping can reduce the tapping torque and solve the problem of the tap broken during the tapping process. The important parameters of vibration tapping are presented in this paper.
