Superalloys such as Inconel X750 are widely used in turbo machinery industry due to their outstanding mechanicalproperties. Inconel alloys are very difficult to machine using conventional mechanical processes like broaching, milling orgrinding. Wire electrical discharge machining (WEDM) is an alternative competitive process to manufacture complexInconel part geometries. However, surface Roughness (SR) of WEDM Inconel components is poorly understood. In thisresearch work an attempt has been made to analysis the effects of input parame ters such as Pulse On time, Pulse Off timeand Peak current, on output parameter such as Surface Roughness. The experiment was performed with differentcombination values of input parameter. An attempt has been made to optimize the machining conditions for SR based on (L9Orthogonal Array) Taguchi methodology. Experiments were carried out under varying pulse-on-time, pulse-off-time, andpeak current. An orthogonal array, the signal-to-noise (S/N) ratio, and the analysis of variance (ANOVA) were employed tothe study the SR in the WEDM of INCONEL X750.
