Electrical Discharge Machining Parameters and Dielectric Fluid

Abstract

This chapter describes the basic working principle of electrical discharge machining. The impacts of both significant and insignificant machining parameters were also detailed. Also, the purpose, properties, and types of dielectric fluid were discussed to better understand the process. This chapter is concluded with describing the benefits of flushing with its types. The rapid impedance of cold dielectric fluid causes an explosive evacuation of molten metal from the electrode and workpiece surfaces. This results in the formation of a tiny crater on the surfaces of the two conductors, which hardens hollow balls of material that are subsequently drained from the gap by the fluid.
