Abstract
Rise in temperature is inevitable in orthopaedic drilling. Massive research had beendone in the field of orthopaedic drilling to investigate the effect of cutting conditions, bone relatedparameters, and drill bit geometric parameters on heat generation and minimum surrounding tissuesinjury. In present research, contradictory conclusions regarding the cutting conditions and drill bitgeometric parameters were observed. Minimum temperature of 31°C was achieved at speed of 186rpm, feed of 0.196 mm/rev, drill diameter of 3.85mm, and drill tip angle of 110°. Response SurfaceMethodology (RSM) was used to develop a mathematical model to predict the type of relationshipbetween inputs and response. It was concluded that the most influencing parameter was drill diameter.
