This paper presents an investigation on the effect and optimization of machining parameters on the kerf (cutting width) and material removal rate (MRR) in wire electrical discharge machining (WEDM) operations. The experimental studies were conducted under varying pulse on time, pulse off time, open circuit voltage, and dielectric flushing pressure. The settings of machining parameters were determined by using orthogonal array. The optimum machining parameter combination was obtained by using the analysis of signal-to-noise (S/N) ratio The optimal search for machining parameters for the objective of minimum kerf together with maximum MRR is performed by using the established mathematical model Grey Relational Analysis (GRA).The optimum values of input parameters for Material removal rate are voltage =102volts ,pulse on time=3µs and pulse off time =3µs.The optimum values of input parameters for kerf width are voltage =93volts ,pulse on time=1µs and pulse off time =1µs. from final grey relational grade X3,Y1,Z3 is the best composition for the wire edm experiment.
