Experimental Investigations of Wire Electric Discharge Machining on Super AlloyMetal Composites

Abstract

A specialized thermal machining technique called wire electrical discharge machining (WEDM) can precisely manufacture items with changing hardness or complex shapes that have sharp edges and are very challenging to machine using conventional machining techniques. This useful technology for the WEDM procedure is based on the typical EDM sparking phenomenon and makes use of the commonly used non-contact material removal method. Since the process's inception, WEDM has developed from a straightforward method for creating tools and dies to the best option for creating microscale parts with the highest level of dimensional accuracy and surface finish quality. The WEDM method has endured over time as a competitive and cost-effective machining alternative that can meet the stringent machining specifications imposed by quick product development cycles and rising cost demands. The possibility of wire breakage and bending, however, has severely hindered the process' full potential and decreased the accuracy and efficiency of the WEDM operation. The various approaches to achieve the ultimate WEDM goals of optimizing the numerous process parameters analytically with the complete removal of the wire breakages, while also enhancing the overall machining dependability, have been thoroughly researched .In this paper a significant amount of study has been done on the WEDM process capacity globally over the years. The purpose of this paper is to examine the research on parametric WEDM process variable effects on various output performance measures. The research also explores the potential of using WEDM technology to machine advanced materials and emphasizes several modelling techniques to forecast optimal machining conditions. This research also emphasizes combined technology, which gains from the advantages of both WEDM and traditional methods. The development and potential direction of research in the WEDM process are covered.
