Wire EDM (WEDM) is a versatile nontraditional machining process used to cut materials of high hardness and to produce very complex and intricate shapes on the wide variety of materials. Hardness of the material is not a constraint for WEDM. This advantage makes the WEDM to cut very hardened materials with ease. Parameters that affect the Material Removal Rate(MRR) and surface roughness mainly consists of pulse on time, pulse off time, discharge current, servo voltage, tension of wire, flushing pressure etc. so, it is very essential to set the parameters that control the outputs in an optimized condition so as get the maximum output. Work has been carried out to find the optimal parameter settings for maximum MRR and minimum kerf (width of cut) for a nickel based alloy, HastelloyC276, a very high temperature, corrosion resistant alloy, using both Taguchi methods and Grey Relational Analysis (GRA).
