Abstract

This paper describe the effect of deep and shallow cryogenic treated brass wire electrodes on the material removal rate (MRR) and the surface roughness (SR) of an EN-31 steel machined by WEDM. Full factorial experimental design strategy is used in the experimentation. Three process parameters, namely type of wire electrode (untreated, deep and shallow cryogenic treated brass wire electrodes), Pulse width, and Wire tension have been considered. Analysis of variance (ANOVA) results indicated that all the process parameters have significant effect on MRR and SR. Scanning electron microscopy (SEM) and Electron dispersive spectrograph ( EDS) highlighted the important features of WEDMed surfaces with cryogenically treated and untreated brass wire electrode. MRR is enhanced and SR is improved with cryogenically treated wire electrodes.
