Abstract: Manufacturing processes have advanced quickly over the few decades, yet they are still not commonly used to their maximum capabilities. Wire EDM is a specialised thermo-electric process capable of accurately machining hard materials with complex shapes. This work concentrated on developing new composite material using stir casting by taking LM5 as the base material with 6% ZrO₂, and by varying graphite to 2%, 3%, and 4% to identify the effect of ZrO₂ and graphite by investigating the effects of the WEDM process parameters on surface roughness and Kerf, and to determine the optimal WEDM parameters using the Taguchi S/N analysis. Hence, the experiments were carried out utilising L₂₇ OA. The parameters which affect the WEDM's characteristics, and also the contribution of machining parameters were determined using ANOVA. A confirmation experiment was carried out as a last step to find the optimal parameters for effective machining of manufactured composites.
