Bone sawing has been widely used in performing bone surgery. However, thermal necrosis, loss of cutting precision and surface damage may occur in cutting process. The primary objective of this research is to improve cutting performance of bone by advantages of diamond wire sawing. Mechanism of material removal, cutting force, temperature and surface quality are analyzed based on experimental results. It is indicated that wire sawing provides small depth of cut, which is effective to obtain ductile material removal mode. Due to small material removal rate per abrasive, thermal energy is low and most of the heat can be taken away by the cyclic wire and bone chips. Consequently, cutting force and temperature in cutting zone are lower than that of traditional sawing. Due to the high efficiency of chip ejection, burrs and fracture are reduced and a significant improvement in surface quality is achieved. Based on cutting experiments with various values of cutting parameters, it is observed that better performance is achievable at higher wire speeds. These results provide a valuable basis for application of wire sawing and understanding of bone cutting mechanisms.

骨锯已广泛用于进行骨外科手术。但是，在切割过程中可能会发生热坏死，切割精度下降和表面损坏。这项研究的主要目的是通过金刚石线锯的优势来改善骨骼的切割性能。根据实验结果分析了材料去除的机理，切削力，温度和表面质量。结果表明，线锯提供了较小的切割深度，这对于获得韧性材料去除模式是有效的。由于每种磨料的材料去除率小，热能低，并且大部分热量可以通过循环线和碎骨屑带走。因此，切削区域的切削力和温度低于传统的锯切。由于排屑效率高，减少了毛刺和断裂，并显着改善了表面质量。基于具有各种切削参数值的切削实验，可以观察到在更高的线速度下可以获得更好的性能。这些结果为线锯的应用和了解骨骼切割机制提供了宝贵的基础。
