Abstract: Bone is an anisotropic material with complex structure. Also, its processing is a basic technology in surgery. The quality of bone processing is the critical factor in surgical treatment effect, implant stability and postoperative recovery time. The mechanical properties of bone are varied from different parts of huma body. Moreover, there are many kinds of surgical instruments, which make the processing methods of bone materials diversified. And those surgical instruments need to process bone material with high precision, high efficiency and low damage. The research of bone cutting mechanism is of great significance to improve the performance of surgical instruments, surgical treatment and rehabilitation effect. Base on the basic characteristics of bone material, this review introduces the cutting mechanism of conventional (i.e. drilling, milling, grinding, sawing) and non-conventional (i.e. ultrasonic, laser, water/abrasive jet) bone processing, clarifying the development status of cutting force and cutting temperature models. Moreover, some existing problems are pointed out and the research thoughts on cutting mechanism of bone material are put forward in this review.

Key words: bone material, cutting mechanism, mechanical cutting, energy field processing, cutting characteristics
