Haste Alloy C276 is a hard to machine superalloy and extensively used in various engineering applications such as aerospace, nuclear reactor and gas turbine industries. Haste Alloy C-276 possess good strength and lower thermal conductivity results in decreased tool life and poor machinability by conventional machining methods. Advanced machining processes have developed over a period to fulfill such kind of demands and claimed to be an appropriate alternative method to traditional metal removal processes. Electrical Discharge Machining (EDM) is one of the advanced machining process which has been employed for machining of hard materials. Electrical Discharge Drilling is one of the variants in EDM process considered as an auspicious method in various engineering applications. This present article details an investigation on electrical discharge machining of nickel based superalloy - Haste Alloy C276 by Taguchi’s methodology. The experiments are devised by Taguchi’s design of experiments approach. A statistical tool Analysis of Variance (ANOVA) has been employed to ascertain the importance of independent process variables on the desired dependent variables.
