This paper describes the procedure of Genetic Algorithm (GA) optimization for reduction of burr geometry in drilling process, modeled using Response Surface Methodology (RSM). Since debarring processes are not yet well automated, it is essential to understand the mechanism of burr formation in drilling and affecting variables to control burr geometry at the production stage itself Second order mathematical models of burr geometry viz. burr height and burr thickness are developed using central composite rotatable design of experiments for drilling of EN8 work pieces. In this work, the effect of cutting speed, feed, drill diameter, point angle and clearance angle on burr height and thickness have been investigated. The RSM models are then employed with GA, which is a search algorithm based on the mechanics of natural selection and natural genetics, to minimize the burr geometry.

Abstract


This paper describes the procedure of Genetic Algorithm (GA) optimization for reduction of burr geometry in drilling process, modeled using Response Surface Methodology (RSM). Since debarring processes are not yet well automated, it is essential to understand the mechanism of burr formation in drilling and affecting variables to control burr geometry at the production stage itself Second order mathematical models of burr geometry viz. burr height and burr thickness are developed using central composite rotatable design of experiments for drilling of EN8 work pieces. In this work, the effect of cutting speed, feed, drill diameter, point angle and clearance angle on burr height and thickness have been investigated. The RSM models are then employed with GA, which is a search algorithm based on the mechanics of natural selection and natural genetics, to minimize the burr geometry.
