Electric Discharge Machining (EDM) is the unconventional machining process used for the machining of hard materials which cannot be machined on the conventional machining process and complicated profiles can also be obtained. The metal is removed by erosion process in all types of electro conductive materials. The eroded material on the surface of work piece and the tool is flushed away from the machined surface by the dielectric fluid. The objective of present work is to study the influence of input parameters on the machining output characteristics. The output characteristics considered are Metal Removal Rate (MRR), Tool Wear Rate (TWR), Surface Roughness (SR) and input parameters taken for the study are peak current, pulse on time, pulse off time and tool lift time for conducting the experiments on Titanium super alloy with copper Tool electrode on electric discharge machine. The experiments are conducted by varying one input parameter and keeping other input parameters constant. The results shown that the MRR, TWR and SR increase with increase in current but at 18A tool start melting. With pulse on/off time MRR and TWR increases initially and there after decreases.
