Optimization of input parameters on WEDM of AZ61-15wt.% Zr C composites via Taguchi technique for sustainability in transportation sectors

Abstract

Sustainability in the transportation sector in terms of materials entails many major areas aimed at reducing environmental effect and promoting sustainability over the long haul. Choosing materials that are lightweight, minimizes fuel usage and emission levels from vehicles. In this investigation, Wire Electrical Discharge Machining (WEDM) behavior of AZ61-15wt%ZrC composites was studied. The AZ61-15wt%ZrC composites were made using the stir casting technique. The specimen was created using the WEDM technique from the manufactured composite. By adjusting the input parameters of Current (I) amps, pulse-ON time (T-ON), wire feed rate (WFR), and pulse-OFF time (T-OFF) in s, at four different levels, the manufactured samples were machined via WEDM. L16 orthogonal array was employed in the Taguchi method of experiment design. Analysis of Variance [ANOVA] was utilized to find which process parameter had the greatest impact on output variables like Material Removal Rate [MRR] and Surface Roughness [SR]. WFR is found to be a substantial input parameter on MRR and T-ON on SR, contributing 32.71% and 74.98% respectively.
