Abstract: In the mechanical industry, properties of high toughness, rigidity, and impact resistance are in high demand. Over the last two decades, machine tools have grown rapidly, but they are still not widely employed to their full potential. The difficulty of achieving effective parameters has attracted the interest of investigators and engineers. In this investigation, stir cast aluminium matrix composites (AMC-LM5/6%ZrO₂/2%, 3%, 4% graphite) were utilised to find the optimal process parameters in WEDM. The importance of improving MRR in WEDM machining cannot be under estimated. To get the intended effects, the trials were conducted by means of the Taguchi approach L₂₇ orthogonal array. ANOVA determines the outcome of machining parameters that influence the normal characteristics as well as the relative contribution of machining parameters. The S/N ratio analysis identifies the parameter that has the greatest influence. The experimental MRR is 9.30 mm³/min, while predicted MRR is 9.46 mm³/min.
