Wire Electric Discharge Machining (WEDM) is one of the important non-traditional machining process used for machining difficult to machine materials like composites and inter-metallic materials, Intricate profiles. In the present work, the study has been made to optimize the process parameters during machining of Hastelloy -C-276 by wire-cut electrical discharge machining (WEDM). This paper presents an effective approach to optimize process parameters for Wire electric discharge machining (WEDM) is extensively used in tool and die industries. Precision and intricate machining are the strengths. While machining, time and surface quality still remains as major challenges. The input parameters are pulse on time (Ton), pulse off time (Toff), wire feed rate and current and voltage were changed during the process. The optimization of analysis is performed by using Genetic Algorithm (GA) method L-27 orthogonal array.
