It is observed that in recent trend INCONEL material has tremendous application in aeronautical, aerospace industry and automobile engineering because of its favorable properties. Therefore “Inconel 825” material has been chosen to machine by EDM. But EDM has a disadvantage of lower MRR. So an experimental investigation has been carried out to study machining parameters of EDM to improve MRR and reducing TWR, surface roughness and kerf width. Here heat treatment process has been studied and applied to improve tool life by reducing tool wear rate. In this experiment Copper tool has modified by changing its grain growth structure by step hardening process and results in both heat treated and without heat treated tools are compared.
