A Review of Experimental Investigation of WEDM to find out performance parameter with powder mix dielectric fluid on Molybdenum High speed steel

Abstract

The demands of high surface finish and machining of complex shape geometries, conventional machining process are now being replaced by non-conventional machining processes. Wire EDM is one of the nonconventional machining processes. MRR and Surface roughness are of crucial importance in the field of machining processes. This Dessertation optimize the TWR in WireEDM for Steel material. The aim of optimization is to attain the maximum MRR and minimum surface roughness and Accuracy. In this study Molybdenum High speed tool Steel is going to use as a work piece, brass wire of 0.25mm diameter is going to use as a tool and distilled water is used as dielectric fluid. As per Literature survey the input parameters have to be pulse on time, pulse off time and Duty cycle, CNT concentration for optimization. Dielectric fluid pressure, wire speed, wire tension and resistance etc suppose to be fixed parameters. The optimal value will be obtain for surface roughness and MRR by using optimization technique, optimized value is obtained separately. Additionally, the analysis will be useful to identify the most important factor. The exponential growth of manufacturing industries and production and the increased need of accuracy and precision throws the spotlight on the nontraditional machining processes.
