Abstract

In today's competitive environment, the desire for superior-performance and affordable composite materials is growing promptly. This study aims to address the need for high-performance materials by creating a low-cost hybrid aluminium metal matrix composite with aluminium alloy LM6 as the matrix material and reinforcement materials of SiC 1%, bagasse ash 1.25%, and fly ash 1.25%. Given that fly ash and bagasse ash are readily available, low-cost industrial and agricultural wastes produced during combustion. The Stir casting technique was adopted for the creation of the hybrid AMMC material. The developed composite is subjected to drilling operation employing Taguchi L9 orthogonal array considering feed rate, drill diameter and spindle speed as the input parameters. To select the best process variables, multi-criteria decision-making (MCDM) was implemented. CRITIC was adopted for weight distribution to each criterion, and MOORA, CoCoSo was employed to rank each alternative. MOORA ranked alternative A3 with spindle speed 60 (rpm), feed rate 82 (mm/rev), and drill diameter 8 (mm), MRR 0.2 (g/s) and Ra 9.7853(μm) as rank 1.Similarly, CoCoSo rank alternative A6 as the best alternative with spindle speed 140 (rpm), feed rate 50(mm/rev), diameter of drill bit 10(mm), MRR 0.0986 (g/s) and Ra 8.4989(μm). Further, studies shows that CoCoSo proved to be the effective techniques compared to MOORA for ranking alternative.
