Multi-objective optimization of EDM machining of Waspaloy employing composite electrode (opens in new tab)

Electrical Discharge Machining (EDM) has emerged as an effective technique for machining difficult-to-cut superalloys such as Waspaloy, which are widely used in aerospace applications due to their superior mechanical strength and thermal stability but exhibit poor machinability under conventional processes. The present study focuses on enhancing EDM performance through the combined use of copper–graphite (Cu–Gr) composite electrodes and eco-friendly dielectric media, along with multi-objectiv...
