Abstract:In clinical orthopedic surgery ， the bone usually needed to be pre-drilled by the doctor in order to im-plant the fixation device. However， the excessive drilling force and poor drilling quality in the process of drilling seriously affected the recovery speed of patients. In this paper ， the traditional drilling and ultrasonic vibration drilling biological bone comparative experiments were carried out， the influences of different spindle speed ，feedspeed ， ultrasonic amplitude on the drilling force were studied ， and the qualities of bone drilling entrance were analyzed. The results showed that； Ultrasonic assisted dilling could effectively reduce the axial force by about23.65% ， when the spindle speed was increased or the feed speed was decreased ， the drilling force decreased； The drilling force decreased with the increase of ultrasonic amplitude； Ultrasonic drilling could effectively im-prove the burr condition of drilling and the drilling quality.
