Abstract: Burr formation in drilling is one of the serious problems in precision engineering and mass production. The exit burr degrades the precision of products and causes additional cost of deburring. Since deburring processes are not yet well automated, the productivity of advanced manufacturing systems is often reduced. However, these processes are labour intensive and add to the total cost of components. Therefore, understanding the drilling burr formation and its dominant parameters is essential for controlling the burr size. This paper describes the Taguchi method based robust design philosophy for minimization of burr size- in drilling. Four parameters, namely, cutting speed, feed rate, point angle and clearance angle were identified and the ranges of the parameters for the present investigation was determined from preliminary experiments. Each parameter was investigated at three levels to study the non-linearity effect of the parameters. Taguchi method based L9 orthogonal array was selected and experiments were conducted as per experimental layout plan. Based on signal to noise ratio analysis, the optimal settings of the process parameters have been determined. Confirmation tests have also been performed to predict and verify the adequacy of the additive models for determining the optimal burr size.
