Bone cutting is an essential procedure of orthopedic surgery, while irreversible bone damage would be inevitably caused using the conventional cutting (CC) method. In this study, an ultrasonic vibration-assisted cutting (UVAC) method was applied in bone cutting to investigate the cutting performance, considering the cutting force and temperature rise, in comparison with CC. In addition, a finite element (FE) model was developed to investigate the cutting mechanism and the influence of a wide range of processing parameters on the performance of cutting bone. The results indicate that the proposed FE model shows good correlation with the experimental results for both cutting force and temperature. UVAC can significantly reduce the cutting force and increase the temperature in comparison with CC from the experimental and predicted results. The cutting force tends to decrease with the increasing vibrational parameters and decreasing cutting speed, while the temperature increases. The verified FE bone cutting model provides an efficient way to assist the optimization of the processing conditions in bone cutting operations.

超声振动辅助骨切割中力和温度的实验和有限元分析。
骨切割是整形外科的基本程序,而使用常规切割(CC)方法不可避免地会造成不可逆的骨损伤。在这项研究中,将超声振动辅助切割(UVAC)方法应用于骨骼切割中,以研究与CC相比切削力和温度升高的切削性能。此外,还开发了一个有限元(FE)模型来研究切削机理以及各种加工参数对切削骨性能的影响。结果表明,所提出的有限元模型与切削力和温度的实验结果具有良好的相关性。从实验和预测结果来看,与CC相比,UVAC可以显着降低切削力并提高温度。切削力倾向于随振动参数的增加和切削速度的降低而降低,而温度则升高。经过验证的有限元骨切割模型提供了一种有效的方法,可帮助优化骨切割操作中的加工条件。
