INVESTIGATION OF TEMPERATURE IN ORTHOPAEDIC DRILLING USING RESPONSE SURFACE METHODOLOGY

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