Abstract : Multi-Criteria Decision Making (MCDM) strategies have gotten much consideration from scientists and professionals in assessing, evaluating and positioning choices over manufacturing industries. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) continues on working attractively crosswise over various application territories. This paper proposes the TOPSIS-based Taguchi enhancement way to deal with deciding the ideal WEDM process parameter for machining of the aluminum hybrid composite using brass wire. The hybrid metal grid composite was manufactured by stir casting process utilizing particulates SiC and graphite each in Al6061 combination. This experiment was outlined with the L 27 orthogonal cluster. The test ponders were directed under shifting Pulse on time, Pulse off time, current, gap voltage, wire speed, and wire tension. The impact of the machining parameters on the kerf width (KW) and surface roughness (SR) is dictated by utilizing an examination of fluctuation. The parameters corresponding to experiment run number 4 are pulse on time 108 units (Level 1), pulse off time 60 units (Level 3), peak current 230 units (Level 3), gap set voltage 60 units (Level 3), wire feed 3 units (Level 1) and wire tension 4 units (Level 1) are the best combination to achieve better surface roughness and kerf width
