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 L 27 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.
Highlights
The aluminium alloy reinforced composites rapidly replace the conventional materials in various industries like aerospace, marine, and automotive
The aim of the present study is to investigate the influence of parameters such as spindle speed, feed rate and drill diameter on torque in of Al-SiC-Gr hybrid composites
The results indicate that the factors V, f, d and the interaction between the factors V*f are highly significant in drilling of composite materials when compared to other interactions and square effects considered
Summary
The aluminium alloy reinforced composites rapidly replace the conventional materials in various industries like aerospace, marine, and automotive. Al-Gr composites are used for bearings, pistons etc due to the existence of peculiar properties such as self-lubrication, low wear rate and less friction. It avoids seizing during inadequate liquid lubrication condition which in turn significantly increases the life, reduces the cost and weight of the component[4,5]. Large size particles have a tendency towards fracture whereas; small size particles increase the strength and exhibit superior strength of MMC14 In this context, the aim of the present study is to investigate the influence of parameters such as spindle speed, feed rate and drill diameter on torque in of Al-SiC-Gr hybrid composites
