EDM Process Using Chemical Reaction of Organometallic Compound

Abstract

In this paper, we examine the EDM process utilizing chemical reactions between organometallic compounds. The oxidization of the dielectric oil facilitates in proportion to working time. The reaction between organometallic compounds causes their transition from a hydrocarbon to a fatty acid containing carboxylic acid, etc. When an oxidized dielectric oil is used in EDM, the metal elements in the electrode and workpiece react to the oxidized oil and organometallic compounds are consequently formed. Several organometallic compounds are olephilic and dissolve in dielectric oil. This denotes that some of the debris from the electrode and/or workpiece metal are dissolved in the dielectric oil. This reaction is often observed as a change in the color of the dielectric oil, such as in the case of the organometallic compound iron, which becomes yellow. The reaction strongly influences the EDM process.Accordingly, by actively utilizing the reactions between organometallic compounds, some of the debris from the electrode and/or workpiece can be dissolved in dielectric oil. This would result in a decrease in debris and provide stability to the EDM process.
