    Ultrasonic cutting is widely used in food processing applications to produce a clean and accurate cut. However, it is yet to be adopted in orthopedic applications, mainly due to the high temperatures that can be generated at the cut site. In this paper a single-blade ultrasonic cutting device is used to study ultrasonic cutting of different materials using materials of cheese, plastic and wood. A comparison between experimental and computed results is used for the relationship between the forming force and tool displacement and visualization which demonstrate close agreement. If deformation is performed under superimposed vibration, the mean stress necessary to maintain plastic now decreases appreciably in comparison with that for purely static deformation, and this decrease is accurately predicted by the finite element (FE) models. The future work aims to perform the experiments at temperatures close to that of the body in order to explore whether it is possible to maintain cutting temperatures within safety limits by controlling the cutting parameters.
