Surgical oscillating saws often induce significant cutting forces when cutting bones, which reduce the accuracy and effectiveness of the surgery. In this study, cutting experiments were performed on fresh bovine bones and simulated bones using saw blades of various tooth and blade edge shapes. Based on the initial findings, a blade was designed to suppress chip clogging, which was clarified to be a detrimental factor that increases cutting forces. The results of cutting experiments demonstrated that the proposed blade shape considerably suppressed clogging, which helped maintain stable and low cutting forces.
