The investigation of machining characteristics is one the most important aspects to take into consideration in the majority of manufacturing processes. Titanium is a super alloy which achieves a high degree of hardness with compressive strength and abrasion resistance Due to these properties; it is one of the most widely used materials in aerospace, aeronautics and nuclear industries. Hence it’s wide use and has high hardness requires unconventional machining such as EDM, the investigation of machining characteristics of Titanium will provide a more economic and efficient method in it. The work material (Ti) was EDM machined with copper electrode by varying process parameters. The machining parameters that we are going to investigation are peak current, Pulse on time and pulse off time and analyses the output parameters such as material removal rate (MRR) and surface roughness (Ra), with the help of Taguchi methods of analysis to obtain the best operating parameter. Investigation indicates that the material removal rate is increases with increasing peak current.

Keywords: Electrical Discharge machining, Titanium, Metal Removal Rate, Surface roughness, Analysis of variance, Taguchi methods
