Evaluation Of Material Removal Rate Using Circular-Shaped Tube Electrode In Electrochemical Machining

The many new materials and alloys that have been developed for specific uses possess a very low mach inability producing complicated geometries in such materials becomes extremely difficult with the conventional methods. Hence, Non-traditional machining has grown out of the need to machine exotic engineering metallic materials, composite materials and high tech ceramics. Electrochemical Machining has been accepted worldwide as a standard process in manufacturing and is capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine. The principle of anodic dissolution of metal theory is the most accepted mathematical model for evaluating material removal from electrodes during electrochemical process. If two suitable metal poles are placed in a conducting electrolyte and a direct current passed through them, the metal on the positive pole get depleted and its material is deposited on the negative pole. Keeping this in view, the present work has been undertaken to finding the material removal rate by electrochemical dissolution of an anodically polarized work piece with a circular-shaped copper electrode.
