Experimental investigation of Wire Electrical Discharge Machining (WEDM) Process Parameters on SS304 using Taguchi method

Abstract

WEDM (Wire Electrical discharge machining) is a nonconventional machining processes used in complicated shapeswith high accuracy which are not possible with other conventional methods .Stainless steel 304 is used in presentexperimental work. Experiments are completed using Taguchi’s method with L9 orthogonal array .The aim of thiswork is to optimize the WEDM process parameters by considering input parameters are pulse on time , pulse off time,peak current and wire feed and experiments are conducted with help of input parameters at three levels andresponse output parameters are MRR (Material removal Rate) and Surface Roughness (SR).Setting of parametersusing by Taguchi’s method.
