Process Parameters Optimization of Electric-Discharge Machining | Optimization of Electric Discharge Machining Parameters for workpiece material AISI SAE D2 tool steel

In order to achieve the best quality characteristics and satisfactory process performance yield; the machining parameters in EDM of workpiece material, AISI SAE D2 tool steel need to be optimized. Taguchi’s philosophy is primarily concerned with the optimization of a single response only. Therefore, in this study a multi-objective hybrid optimization technique combining PCA, TOPSIS integrated with Taguchi method; and another efficient technique MOORA-PCA combined with Taguchi method has been employed successfully for optimizing performance parameters of EDM reaching an optimal parameter setting for machining of advanced materials like AISI SAE D2 tool steel.
