Predicting burr size in drilling of AISI 316L stainless steel using response surface analysis

This paper describes the development of mathematical models to investigate the effects of process parameters on burr size during drilling of AISI 316L stainless steel. The Response Surface Methodology (RSM) based burr size models using central composite rotatable design of experiments were employed for this purpose. The study highlights the effects of cutting speed, feed, drill diameter, point angle and lip clearance angle on burr height and burr thickness. Response surface curves were plotted to show the important interaction effects of process parameters on burr size. The analysis reveals that feed, drill diameter, point angle and lip clearance angles have considerable effects on burr size.
