Abstract: In this paper the accuracy of drilling miorevoid by ultrasonic vibration or electromagaitic vibration in the direction of axis has been studied. The results show that the axial vibration drilling can obviously improve position accuracy of entering drilling, diameter accuracy of microvoid and roundness of microvoid.
