Abstract

This paper presents an experimental investigation on torque in drilling of aluminium hybrid metal matrix composite (Al-15%SiC-4%Gr). The drilling parameters used here was spindle speed, feed rate, drill diameter for 3 levels. The optimized parameter of aluminium hybrid composite was found by taguchi’s L27 orthogonal array experimentation. The significant parameter was found by ANOVA method. Minitab software has been used for Taguchi’s technique. The fabrication technique adopted was stir casting technique. The experiments are conducted on computer numeric control vertical machining centre using multifaceted carbide drills of 4 mm, 8 mm and 12 mm diameter under dry drilling conditions. A response surface analysis is carried out. The effect of drilling parameters on Torque is studied and presented. The results indicated that feed rate is the main parameter which influences the Torque in drilling of hybrid metal matrix Composites.
