Abstract

In order to improve the quality and reduce mechanical damage during bone drilling in surgeries, the three key parameters in drilling by the Kirschner wire are experimentally studied based on the response surface method (RSM). And through response surface analysis, a predictive model of each factor and response value is established. The experimental results found that when the beveled plane angle Φ = 10°, the rotational speed n = 1200 rpm, and the feed speed vf = 20 mm/min. Not only the drilling force is minimized, the delamination coefficient and the height of the hole exit burr are also the minimum. Therefore, the smaller bevel angle, the feed speed and the higher rotation speed can effectively reduce the drilling force, the delamination factor and the height of the hole exit burr, and significantly improve the drilling quality.
