Experimental Investigation for Optimum Process Parameters in Wire Cut Edm Process Using Taguchi Method Duplex Steel 2507

Abstract

In this project, experiments and analysis have been conducted to investigate the effect of process parameters of Wire-cut EDM on the performance measures such as material removal rate (MRR) and surface finish. The input parameters selected are pulse on time, pulse off time, discharge current and wire feed. An optimization technique namely, grey taguchi method has  been employed to identify the optimum parameters of the wire-cut EDM process for cutting 2507 grade duplex stainless steel. The effects of each control parameter on the performance measure have been studied individually using the plots of signal to noise ratio. Response surface methodology has been applied to generate a mathematical model for each output parameter in terms of the input parameters. A detailed description of the microstructure of the material used has been given which explains the properties of the material.
