摘要:在临床骨外科手术中，医生通常需要对骨进行预钻孔，以便植入固定装置，但是，骨钻孔 过程中钻削力过大或钻孔质量差，均会严重影响患者术后恢复速度。为此，对传统钻削与超声振动钻削生物骨进行对比试验，研究不同主轴转速、进给速度和超声振幅对钻削力大小的影响规律，分析骨钻孔入口质量情况。结果表明：超声辅助钻削可以有效降低轴向力，降幅约为 23.65％，当增大主轴转速或降低进给速度，钻削力均随之减小；钻削力随着超声振幅的增加而减小；超声钻削可以有效改善钻孔毛刺情况，提高钻孔加工质量。

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.
