Investigations into Wire Electrochemical Machining of Stainless Steel 304
Wire Electrochemical Micromachining (Wire-ECMM) is now under investigation by researchers around the globe due to the agility it offers to manufacturers over other advanced machining processes. A key application of this process is in cutting different shapes out of parent workpiece material of variable or uniform thickness by moving the tool along a predetermined path. The key features associated of a cut cavity (kerf) in Wire-ECMM are the fillet radius (FR) along the thickness of workpiece material, corner radius (CR) at curves and width of the kerf (S). In the present work, the dependency of these characteristic features is examined on different process parameters like applied potential(V), electrolyte concentration (C) and tool feed rate (f). Based on the results, optimum values of these parameters are identified and features like circle, triangle and square spiral are machined on Stainless steel 304.
