Investigating and analyzing parameters affecting the bone drilling process using the Taguchi method.

The bone drilling process is a crucial and widely used machining technique in the field of surgery and medical engineering. It is particularly prominent in orthopedic surgery, fracture treatment, bone sampling, and dentistry. The most important complication that may occur in bone removal surgery is the increase in temperature from the permissible range and causing thermal necrosis in the bone tissue. In general, if the temperature of the bone piercing process exceeds 47°C, thermal necrosis occurs. In case of thermal necrosis, bone fixation is not done well. In recent years, researchers did not achieve acceptable results in this field due to the lack of efficient optimization methods and the failure to consider all parameters affecting the bone drilling process. Also, it was not possible to achieve the best effective parameters to prevent thermal necrosis. Therefore, in this article, in order to prevent this issue, along with the precise design of the experiments, a relatively accurate method has been presented as a solution to control the temperature and axial force in order to optimize the effective parameters on the bone drilling process and improve the bone drilling process. In this article, the Taguchi optimization method is used for this purpose, and this method performs the optimization process with high accuracy in a shorter period of time compared to other optimization methods.
