Experimental Investigation of Process Parameters in Electrochemical Machining

Abstract

Electrochemical machining is a non-conventional machining process worked with a principle of Faraday’s law. It is one of the best alternatives for producing complex shapes in advanced materials used in aircraft and aerospace industries. However, the reduction of the stray material removal continues to be a major challenge for industries in addressing accuracy and improvement. It is very difficult to appliance a high strength, heat-resistant material into complex shapes by conservative techniques, but such materials can be effectively machined by electrochemical machining (ECM) method. This experiment highlights features of the development of a comprehensive mathematical model for correlating the interactive and higher-order influences of various machining parameters on the dominant machining criteria, i.e. the metal removal rate and the surface roughness phenomena, through Taguchi method and RSM method using the pertinent experimental data as obtained by experiment.
