Unconventional machining process finds lot of application in aerospace and precision industries. It is preferred over other conventional methods because of the advent of composite and high strength to weight ratio materials, complex parts and also because of its high accuracy and precision. Usually in unconventional machine tools, trial and error method is used to fix the values of process para...

Electric Discharge Drill Machine (EDDM) is a spark erosion process to produce micro holes in conductive materials. This process is widely used in aerospace, medical, dental and automobile industries. As for the performance evaluation of the Electric discharge drilling machine it is very necessary to study the process parameters of machine tool. In this research paper a brass rod 2 mm diameter w...
