Abstract : In this present experimental work, the effect and advancement of machining control parameters over kerf and surface quality in wire cut electrical discharge machining operations were analyzed. The hybrid metal reinforced composite was manufactured by a process named as stir casting utilizing particulates of graphite & Silicon carbide each in Al6061 combination. The analyses were outlined with Taguchi L 27 design matrix. WEDM parameters resemble pulse on time, current, Pulse off time, gapset voltage, wire tension & wire speed are considered. The impact of the machining parameters on the kerf width (KW) and surface roughness (SR) is dictated by utilizing MOORA method. The parameters corresponding to experiment run number 7 are pulse on time 108 units (Level 1), pulse off time 60 units (Level 3), peak current 230 units (Level 3), gap set voltage 60 units (Level 3), wire feed 3 units (Level 1) and wire tension 4 units (Level 1) are the best combination to achieve better surface roughness and kerf width
