Multi-response Optimization of Wire Electrical Discharge Machining Process Parameters for Al7075/Al2O3/SiC Hybrid Composite Using Taguchi-based Grey Relational Analysis

Seshappa Angadi and Anjaneya Prasad Bannoth To understand how various process parameters in wire electrical discharge machining (WEDM) affect surface quality metrics such as surface roughness and kerf width, Using an L27 orthogonal array, researchers looked at a hybrid metal matrix composite made of Al7075 alloy, 7.5% aluminum oxide (Al2O3), and 7.5% silicon carbide (SiC) nanoparticles and a technique that used inert gas assistance during the electromagnetic stir casting procedure.
