Burr Minimization in Drilling of Al6061/SiCp Metal Matrix Composite

Article Preview

Abstract:

Most machining processes produce burr as a result of plastic deformation. Exit burr strongly affect product quality during assembly and it is difficult to remove them easily. This work aims at minimizing burr produced in drilling of Al6061/SiCp composite fabricated through stir-casting process using HSCO drill. Analysis of experimental results using ANOVA indicated the influence of cutting conditions and drill geometry in reducing the thrust force as well as burr size. Keywords: Drilling, Al6061/SiCp, HSCO drill, ANOVA, Thrust force, Burr
