Study of parametric optimization of burr formation in step drilling of eutectic Al–Si alloy–Gr composites
چکیده انگلیسی

In this study, the effect of the step drill's geometries such as step angle, step size and cutting parameters such as feed and spindle speed on the exit burr height was investigated for burr minimization in drilling of Al–Gr composites which are fabricated through squeeze casting method. The experimental study was conducted as per the L27 orthogonal array of Taguchi method to find the optimum drilling parameters, and analysis of variance (ANOVA) was performed to investigate the influence of parameters on the burr height of composites during drilling. Confirmation tests were conducted to validate the test results. Results revealed that feed, step angle, step size and spindle speed were the significant parameters in the formation of exit burr.
