Investigation of Brass Electrode and Titanium Alloy on Electrical Discharge Machine

Abhishek Verma


Electrical discharge machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). The higher wear ratio is found during machining of titanium alloy using a brass electrode. An attempt has been made to correlate the thermal conductivity and melting point of electrode with the MRR and electrode wear. The MRR is found to be high while machining titanium alloy using brass electrode. During machining of titanium alloy using copper electrodes, a comparatively smaller quantity of heat is absorbed by the work material due to low thermal conductivity. The tool electrode materials used are brass. Experiments are conducted using face centered central composite design. During machining of titanium alloy using aluminum electrodes, the material removal rate and electrode wear rate are only average value while machining of titanium alloy using brass and copper electrodes.
