Abstract

In medical practices, high speed surgical drills are usually used when drilling the screws into the fracture bones. The friction between the drill bit and the bone during the drilling process will generate heat. This heat then will produce the thermal necrosis into the bone. Parameters involve in heat generation are spindle speed, drill bit diameter, drill bit point angle, feed rate, and the bone's properties. The focus will be on the setup of the experiment test rig to perform the bovine bone drilling and the thermal analysis of this experiment using ANSYS. The principles of heat transfer mechanism and complex thermo-mechanical equation from the machining theory will be used alongside anisotropic properties of the bone. This project will look into the problem of high heat generation during drilling process and the process pararneters that will control the drilling temperature. Drilling tests were performed on mild steel cylinder bar and bovine bone femur. The effect of spindle speed and feed rate on the temperature was explored. The temperature during drilling is linearly increases with the depth of the specimen.
