Relationship between Wire Diameter and Processing Shape in Micro-Electrical Discharge Machining (micro-EDM) on Gelatin Gel

Abstract

When Micro-Electrical Discharge Machining (micro-EDM) is utilized for processing of gelatin gel, processing with resolution of several micro-order is possible. It is known that machining shape changes by changing the gap and applied voltage as a parameter for micro-EDM on gelatin gel. In this research, we investigated the change in the shape of the workpiece when changing the thickness of the electrode used for the discharge. Using this result, we consider the shape of the wire necessary to realize highly accurate machining.
