Abstract

Abstract. Precision in surgical bone drilling is essential for restoring bones mobility and function. However, the intricate nature and fiber-reinforced composite structure of bones inherently pose drilling-induced mechanical damage to the bone surface, affecting the primary stability necessary for implant anchorage and therefore leading to implant failure. The critical need for enhanced hole quality and damage reduction has spurred investigations into the optimal drilling parameters, novel drilling tools and alternative machining techniques. This study rigorously investigates the effect of the cutting speed and feed rate during axial drilling employing a center drill. It extends toward a comprehensive analysis of forces, temperature and mechanical damage, with a particular emphasis on delamination assessment. Then, the optimal parameters are established using the Tool-Material Couple (COM) optimization strategy. Subsequently, a novel approach of orbital drilling in bones is introduced for hole quality enhancement when compared to the conventional technique. This investigation serves as a foundational step for a more comprehensive study that ventures into the innovative application of orbital drilling in orthopedics.
