摘要：

In order to study the influences of axial LFVAD method on drilling forces and temperature rises in cortical bone drilling processes, experiments of the drilling forces and temperature rises in conventional drilling and axial low-frequency vibration-assisted cortical bone drilling were conducted based on a self-developed LFVAD equipment. Drilling forces and heat generation rate models were presented. Experimental results show that the feed force and torque in axial LFVAD are obviously reduced, and the temperature rises are reduced by 3~5℃. It is found that the spindle speed is the most significant influence factor of drilling forces and temperature rises. Double objective optimizations were performed by statistics. Results from the model are consistent with experimental data. It may be regarded that periodic separation of drill bit and bone tissue generated by axial LFVAD is the main reason for the reductions of drilling forces and temperature rises. © 2021, China Mechanical Engineering Magazine Office.
