Experimental Investigation of Material Removal in Elliptical Vibration Cutting of Cortical Bone

Abstract To benefit tissue removal and postoperative rehabilitation, increased efficiency accuracy reduced operating force are strongly required in the osteotomy. A novel elliptical vibration cutting (EVC) has been introduced for bone compared with conventional (CC) this paper. With assistance of high-speed microscope imaging dynamometer, material removals cortical their forces from two regimes were recorded analysed comprehensively, which clearly demonstrated chip morphology improvement average reduction EVC process. It also revealed that tool could promote fracture propagation along shear direction. These new findings will be important theoretical practical values to apply innovative process surgical procedures
