【 摘 要 】

In this present experimental study, the effect and advancement of machining parameters on cutting speed (CS) in wire electrical discharge machining (WEDM) operations were studied. The hybrid metal matrix composite (MMC) was manufactured by process named as stir casting utilizing particulates of Silicon carbide and graphite each in Al6061 combination. The analyses were outlined with response surface methodology. WEDM parameters resemble Pulse on time, current, Pulse off time and control speed are considered. The optimized parameters are Pulse on time (Level 3), Pulse off time (Level 1), peak current (Level 2) and control speed (Level 2) are the best combination to achieve best material removal rate. Pulse off time, control speed, Pulse on time and discharge current have considerable effect and most influenced control parameters on CS.
