Abstract
Electrical discharge machining (EDM) drill is a kind of EDM processes to machine deep, micro sized holes of hard machining material. Since it works regardless of materials strength or stiffness, it is known that EDM drilling is effective than conventional drilling for the micro-drilling. The accuracy of a machined surface is determined by electric discharge parameters. Thus, in this study a EDM-drilling plan with the experiment of design (DOE) is set up to analyze the characteristics of Pass-Through Holes in EDM-drill and then the relationship between the four major discharge parameters and machined hole accuracy is addressed in terms of hole diameter and surface roughness. Finally, the tendency in each parameters of EDM-drilling is studied with average response value (ARV).
