Detail:

Rotary ultrasonic bone drilling named as RUBD has been successfully attempted to minimize the forces, torque temperature and microcracks during bone drilling. In order to perform the experimental investigations to find out change in temperature, force, torque, temperature and microcracks with RUBD using diamond coated hollow tool on bone, rotary ultrasonic tool assembly was designed and fabricated in house. The drilling experiments were planned and carried out on porcine bones using design of experiments (Response Surface Methodology). Analysis of variance (ANOVA) was carried out to find the effect of process factors such as rotational speed, feed rate, drill diameter and ultrasonic vibrational amplitude on the force and torque

Link: The results of microcracks by SEM revealed that RUBD process offered a lower force, torque, temperature and minimum microcracks, making it a potential process for bone drilling in orthopaedic surgery. It was also found that RUBD generated a much lower temperature, force and torque as compared to the CSBD.
Problem Scale: Around the world
