Surface Quality Analysis of Titanium Alloy in Electrical Discharge Machining Using Aluminum Electrode in Fine Machining
Keywords:
electrical discharge machining, Titanium, Surface roughness, Taguchi methodAbstract
Surface roughness is an indicator commonly surveyed in other previous studies and the quality of the surface due to surface roughness (SR) reduction reduces machining time of the machining operations. This paper report on the results of SR in electrical discharge machining (EDM) using aluminum electrode for titanium alloy. The process parameters: pulse on-time, electrical current and voltage were used, and researh method was the Taguchi. The influence of the parameters to SR was evaluated through the average value. Results showed that, the parameters pulse on-time and voltage is the most influence to surface roughness (SR). Analysis of the surface layer after EDM using aluminum electrode has shown that the quality of the surface layer has been increased significantly.
