Micro-Electric Discharge Machining (Micro-EDM) is a recognised material removal process for the manufacturing of micro components/parts, micro features, micro cavity and micro holes on difficult to machine materials like aluminium matrix composites, titanium alloy and nickel-based alloys. It plays a major role in miniaturisation process particularly in micro dies/moulds, biomedical devices and micro electromechanical system (MEMS) etc. In Micro EDM process, material removal takes place by melting and vaporisation through series of discharge sparks. Besides erosion of the work piece material, inherent aspect of the process tends to material removal, tool wear, surface finish and dimensional inaccuracy in the machined micro components or parts. The comprehensive review of Micro-EDM of aluminium alloy and aluminium matrix composites and challenges are presented especially to improve machining performance, such as material removal rate, surface finish, tool wear rate and dimensional accuracy.
