Abstract :

Abstract- Electrical Discharge Machining (EDM) is capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, composites, super alloys, ceramics, carbides, heat resistant steels etc. being widely used in die and mold making industries, aerospace, aeronautics and nuclear industries. In the present work ZA-27 alloy is used as work piece which was machined by different electrode materials such as copper, graphite and brass. Machining parameters used were type of electrode, current and pulse on time. And the output parameters found were MRR and TWR. The settings of machining parameters were designed according to Taguchi’s L9 orthogonal array and significant machining parameters were identified using Signal to noise ratios and ANOVA. The results reveal that high material removal rate was achieved by increasing the current, and less tool wear was found for copper electrode.
