In this paper, various parameters of EDM are studied. By using Design of Experiment techniques these parameters are obtained to get the better surface finish on the Titanium alloy (Ti-6AL-4V). The adequate selection of manufacturing conditions is one of the most important aspects to take into consideration in the die-sinking electrical discharge machining (EDM) of conductive materials. In this work, the input parameters selected for the experimental study were Current, Pulse On Time and Pulse off Time. The response parameter that was studied in this test was surface roughness. On the basis of Input and response parameter an orthogonal array ‘L9’ was used for the statistical analysis. The Minitab version 15 software was used to get optimal values for the test and then a confirmation experiment was done in order to validate the result.
