The research objective is to carry out experimental analysis on Electrochemical Machining(ECM) of Hastealloy material. Hastealloy is a form of Nickel based superalloy material provides application in the field of chemical, aerospace and power plant industries due to high strength and corrosion resistance behaviour. The influence of ECM process variables include current, frequency and duty cycle on machining time and overcut are investigated with Sodium Nitrate and Sulphuric acid electrolyte.

From the results it was observed that current has primary influence on the machining time and overcut and duty cycle has secondary influence. From the investigation it is inferred that overcut is mainly affected by current. It is due to the effect of stray current and high current densities near the machining zone.
