Wire Electrical Discharge Machine (WEDM) is an advanced machine tool, extensively used to machine hard to cut materials like nickel, titanium and other super alloys. Selection of WEDM process parameters to yield the desired level of performance measures like Material removal Rate (MRR) and Surface Roughness (SR) is crucial from quality and economic viewpoints. In the present work an attempt has been made to investigate the effect of WEDM process parameters such as pulse on time, pulse off time and peak current in machining of AISI D2 steel. A 2-level factorial of full factorial design has been used for experimental plan. The significance of process parameters are estimated by ANOVA analysis. Mathematical prediction models are developed for MRR and SR by FFD. Using optimization process of TLBO and also Grey Relation Analysis optimize the calculation.
