Wire Electro Discharge Machining (WEDM), Material Removal Rate (MRR), Surface Roughness (SR), Taguchi’s Orthogonal Array, Ratio Signal-To-Noise Ratio (S/N Ratio), Wire Feed (WF), Wire Tension (WT), Analysis Of Variance (ANOVA)


Present study has been made to optimize of surface roughness and material removal rate in EN 24T steel. Two input parameters wire feed, wire tension were chosen as variable to study the process parameter. The analysis of variance (ANOVA) was carried out for study the effect of process parameters on process performance. In addition mathematical models have also been developed for response parameter. Properties of the machined surface have been examined by surface roughness tester. For the different values of the two input parameters developed L9 orthogonal array by taguchi method. Here the surface roughness is measured with the help of surface roughness tester SJ-210 This tester is diamond tip which measure accurate value of surface roughness. Second response parameter material removal rate is measured with the help of measurement of volume and cutting time The effect of each control factor on the performance measure is studied individually using the plots of signal to noise ratio The study demonstrates that the WEDM process parameters can be adjusted so as to achieve better metal removal rate and surface finish.
