Electrical Discharge Machining vs. Other Machining Processes “There’s more than one way to skin a cat,” as the old expression goes. TOOL MATERIAL . He was an English physicist. Electric discharge machining (EDM), or spark erosion is originally a high-precision manufacturing process. Innovation from electrical discharge machining to direct milling On the basis of the current research and future projections, one can expect increased application of electrical discharge machining (EDM) in … EDM machining process is also known as spark erosion machining. It was first observed in 1770 by Joseph Priestley. Continue Reading. ORIGINAL ARTICLE Advantages of carbon nanotubes in electrical discharge machining C. Mai & Hong Hocheng & S. Huang Received: 8 March 2011 /Accepted: 13 June 2011 # Springer-Verlag London Limited 2011 The Principle. Electrical Discharge Machining, EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. During this machining process, a small portion of metals is also eroded away, leaving a small cater. UNIT-III 2. Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. How Electron Beam Machining Process Works? It is widely used, for example, for the production of forging or stamping tools made out of extremely hard metal. The method is similar to an electric spark that burns a hole in the metal that it contacts. The spark produces heat, which burns away the metal … Electric Discharge Machining is a non- traditional concept. Principle, working and applications of Electric Discharge Machining process Principle: Electric discharge machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool and the workpiece.
