Abstract
Machining of high-strength alloy is needed for special requirements requiring less wear, such as sliding objectives in applications like cams, gears etc. High-strength alloy material profile machining is challenging in conventional machining; Wire-EDM is one of the machining processes to fulfil the requirement with a good surface finish. The present work is an experimental study on material removal rate in Wire-EDM machining on S31803 Duplex Stainless Steel (DSS) material at different thicknesses. Thickness is considered as 5 mm, 10 mm, 15 mm and 20 mm where the nozzle distance altered as 19, 29, 39 and 49 with pulse off time 1,2,3,4 s. L16 orthogonal array from Taguchi method of experiments considered for the present study. Material of 10 mm thickness with 4 s pulse off time at 29 nozzle distance gives better material removal rate when compared with other samples.
