Electrochemical machining (ECM), a metal removal process based on the laws of electrolysis, was developed for shaping high strength heat‐resistant alloys that are difficult to machine by conventional techniques. at the anode (workpiece) and cathode (tool) and within the electrolyte. Electrochemical Machining process, the combination of electrical energy and chemical energy makes the removal of material from the surface of a work-piece.It works on the principle of Faraday's law of electrolysis. at the anode or workpiece and at the cathode or the tool along with within the electrolyte. %%EOF This process may be considered as the reverse of electroplating with some modifications.

Although a large number of those references appeared in what might be described as ‘non-learned’ journals, this still leaves the potential student with a difficult task if he wishes to review the state of the art. Before dive into the main topic let me give you some idea related to ECM. Process During ECM, there will be reactions occurring at the electrodes i.e. 950 0 obj <> endobj startxref ����8�� � Electrochemical Machining 1. 0000002504 00000 n To the end of 1974 the scientific literature contained over 1200 articles on electrochemical machining (ECM) [1]. %PDF-1.3 %���� %PDF-1.4 %���� 0000017559 00000 n Using ECM techniques, hard metals can be shaped as reliably as soft ones and the rate of machining does not depend on hardness. Electrochemical machining (ECM) is a non-conventional manufacturing process which relies on duplicating the shape of the tool electrode into the workpiece via the anodic dissolution of the workpiece. Michael Faraday discovered that if the two electrodes are placed in a bath containing a conductive liquid and DC potential (5-25V) is applied across Electrochemical machining is a relatively new technique, on ly being introduced as a commercial technique within the last 70years. Its use is limited to electrically conductive materials.
