Wire electrical discharge machining allowed success in the production of newer materials, especially for the aerospace and medical industries. Using WEDM technology, complicated cuts can be made through difficult-to-machine electrically conductive components. The high degree of the obtainable accuracy and the fine surface quality make WEDM valuable. Inconel is one of the newer materials that are developed to be hard, strong and temperature resistant which is widely used in turbo machinery industry due to their outstanding mechanical properties. However the challenge lies in optimum performance of WEDM and machining constraints with Inconel-718, so in this paper Inconel 718, was machined using WEDM and further with two different electrodes materials zinc coated brass and plain brass. Anova, is used to get the most influencing parameter out of discharge energy, pulse off, wire feed, wire tension, and flushing pressure on cutting rate, accuracy parameter kerf width. It has been found that discharge energy released is determining factor for both the response variables and there is considerable effect of electrode materials.
