Abstract

Electric discharge machining has the potential to maintain surface topography and produce less stresses and destruction to the components. In this machining there is no contact between the tool and the work piece. The spark generated due to the electrostatic field generation between tool and the work piece. The objective of this experimentation was to create guidelines for electric discharge machining of Al 65032. Aluminum alloy 65032 is one of the aluminum alloy widely used for air craft components like making prototypes, fulsages, critical engine parts. In EDM machine there are certain input parameters like current, pulse on time, duty cycle and pulse off time etc. which must be selected to get the desired output like Metal removal rate, Tool Wear rate and Surface roughness. The optimum process parameters were designed using Taguchi approach and the parametric contribution of each factor was determined by analysis of variance technique using MINITAB 17 Software. After that optimal setting for material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR), respectively was found.
