Study on Optimization of WEDM Process Parameters on Stainless Steel

Stainless steel is a material which has high corrosive resistance and oxidation at temperature with the combination of chromium, nickel, niobium as primary constituent. This difficult to machine complex shape taken by using wire cut electric discharge machining. Wire electrical machining nontraditional process widely for cutting shapes. review paper involves EDM optimization parameters. Pulse interval, pulse duration, feed, voltage, mean current are operational The Taguchi orthogonal array method, analysis variance (ANOVA), grey relation (GRA) methods different kinds various materials, result best removal rate (MRR) surface roughness (SR) analyzed. work suggests most influencing parameters method materials.
