Abstract
This research paper focuses on the analysis of Wire Electrical Discharge Machining (WEDM) performance on A17075/B4C/CNT hybrid metal matrix composite. This study aims to examine the impact of different machining parameters on surface roughness, material removal rate, and kerfwidth in the WEDMprocess. Experimental tests are conductedto examine the effects ofparameters such as wire type, wire feed, wire tension, pulse-off time, and pulse-on time on the machining performance of the hybrid metal matrix composite. The Taguchi design of experiments technique was employed to design number of experiments required to determine the optimal input parameters andthe L16 orthogonal array was chosen. To identify the ideal set ofinput parameters, grey relation analysis is also carried out. Ultimately, Grey Relation Analysis proposed AIB2CID2E1 are the optimal values of the control factors for better machiningresponses.
Keywords- Hybrid MMC, Stir casting, Wire Electrical Discharge Machining, and Grey Relation Analysis method.
