Electrochemical Machining of Aluminium Metal Matrix Composites

High performance aluminium based metal matrix composites possess low machinability characteristic. Electrochemical machining (ECM) is one of the advanced machining processes, used for machining of these newly developed exotic materials. This article critically reviews the research work on experimental investigations on ECM of aluminium matrix composites. Besides, recently developed techniques such as abrasive assisted electrochemical machining, electrochemical grinding, electrochemical micromachining, and electrochemical drilling are explored in the processing of aluminium metal matrix composites.
