Parametric study and analysis of WEDM of Inconel-625 using desirability

Inconel 625 is one of the most versatile nickel-based super alloy used in the aerospace automobile chemical processing oil refining marine waste treatment pulp and paper and power industries. Wire electrical discharge machining (WEDM) is the process considered in the present text for machining of Inconel 625 as it can provide an effective solution for machining ultra-hard high-strength and temperature-resistant materials and alloys overcoming the constraints of the conventional processes. The present work is mainly focused on the analysis and optimization of the WEDM process parameters of Inconel 625. The four machining parameters that is pulse on time pulse off time spark gap voltage and wire feed have been varied to investigate their effects on three output responses such as cutting speed gap current and surface roughness.
