ABSTRACT : |
IN current research article, the effect of wire electrical discharge (WEDM) machining parameters such as current intensity, pulse on time, pulse off time and wire feed on material removal arte (MRR) in Inconel 625 super alloy were studied. The experiments are carried out as per design of experiments approach using L9 (3*4) orthogonal array. The results are analyzed by analysis of variance and response graphs. This experimentation study it is found that different combination WEDM process parameters are required to achieve higher material removal rate. Pulse on time and current are found the most effective parameters. SEM analysis is also done for material characterization.
