ABSTRACT
Electric Discharge machining is used to pro-duce complex shapes that would be difficult to produce in conventional machine tools and also good surface finish can be obtained in EDM. The work material EN24 is machined by using copper as electrode. The EN24 contains nickel, chromium and molybdenum and it is used in automobile and aircraft transmission components .For this reason, the EN24 is experimentally investigated with the machining parameters for achieving maximum MRR and minimum and surface roughness.[1] The ANOVA is also used to identify the ma-chining parameter responses on MRR and SR. The input parameters are peak current, pulse on time, discharge voltage and pulse off time. Regression equations are formulated based on the experimental results. The effects of input parameters are analyzed on MRR and SR.
