Influence of drilling parameters on bone drilling force and temperature by FE simulation and parameters optimization based Taguchi method

During bone drilling surgery, the bone drill can generate drilling force and frictional heat, which may lead to mechanical and thermal damage to the bone tissue. This paper presents a finite element (FE) simulation of bone drilling for cortical and cancellous bone, analyzing the influence of drilling parameters on bone drilling force and temperature. The simulation results reveal the change laws of axial force and temperature during different density bone drilling for var-ious parameters. To optimize the bone drilling parameters, the Taguchi method is applied to con-duct bone drilling simulation experiments based on the FE simulation model. The optimal values of axial force and temperature are predicted and calculated under the condition of optimal drilling parameters. Furthermore, a robot bone drilling experiment platform is used to verify the bone dril-ling FE simulation model and the optimal parameters. The research demonstrates that the FE sim-ulation model effectively explores the influence of drilling parameters on bone drilling force and temperature, while the Taguchi method optimizes the drill parameters to minimize the mechanical and thermal damage to the bone tissue.(c) 2023 THE AUTHORS.
