Machining in Electrical Discharge Machining (EDM) using Graphite Electrode

Sumit Kumar


In modern industry demands of titanium alloy is increasing day by day. Because it has many several characteristics such as low thermal conductivity, low elastic modulus. Application of Titanium and its alloys now a day in different field such as aerospace industry sports car etc. Therefore, it is replacing different metal such as aluminium in many applications. It has high corrosion resistance and high strength – to – weight ratio so these material are also called super alloy. By using conventional machining process titanium and its alloy are very difficult to machining. So Non–conventional machining process such as EDM is used to machine these type of hard material such as titanium alloy. Because EDM can provide better surface finish rate and machine complicated geometry and profile. So producing complex cavities in die EDM has been widely preferred. There are no mechanical vibrations and chatter produced in machining procedure.
