A Study of the Impact of Multiple drilling parameters on Surface Roughness, Tool wear and Material Removal Rate while Drilling Al6063 applying Taguchi Technique

Abstract

The goal of this project is to see how different drilling parameters like spindle speed (600, 900, 1400 revolution per minute), feed rate (0.10, 0.16, 0.22 mm per revolution) and drill tool diameter (6, 8 mm) affect surface roughness, material removal rate and tool wear while drilling Al 6063 alloy with an HSS spiral drill using Taguchi method. The impact of different drilling settings on the accuracy of the drilled hole is analyzed using S/N (signal-to-noise) ratio, orthogonal arrays of Taguchi, regression analysis, and analysis of variance (ANOVA). CNC Lathe Machineis used to perform a number of experiments with the help of L18 orthogonal arrays of Taguchi. MINITAB 19, a commercial software tool, is used to collect and evaluate the results of the experiments. For establishing a correlation between the selected input parameters and the quality aspects of the holes made, linear regression equations are used. The experimental data are compared to the expected values, which are quite similar.
