An Investigation on Thermal Necrosis, Modeling and Optimization of Temperature in Bovine Cortical Bone Drilling Process

In this paper a mathematical model is developed to able surgeon to predict the temperature of the process based on tool’s rotational speed, feed rate, tool diameter and effective interactions between parameters. The allowable range of parameters in bone drilling operation is introduced to obtain a quick and swift operation as desirable. Experiments were designed and modeled using response surface method and to ascertain operation condition, optimization was performed. Results show that within the range of the variables, with an increase in tool diameter and cutting speed the rate of temperature increment, boosts up. It is noted that the behavior of the feed rate is complex where in this paper is investigated precisely. Introduced response surface model is able to anticipate temperature behavior based on input parameters.
