EDM Using Chemical Reaction of Organometallic Compounds

Abstract

In this study, electrical discharge machining (EDM) utilizing chemical reactions between organometallic compounds is examined. The oxidization of the dielectric oil facilitates the machining process depending on working time. When oxidized dielectric oil is used in EDM, metal elements in the electrode and workpiece react with the oxidized oil, and organometallic compounds are consequently formed. Several organometallic compounds have lipophilic property and dissolve in dielectric oil. This indicates that some debris from the electrode or workpiece metal can be dissolved in dielectric oil. Accordingly, by actively utilizing the reactions between organometallic compounds, some debris from the electrode or workpiece can be dissolved in dielectric oil. This would result in a decrease in the amount of debris and provide stability to EDM.
