Power or energy saving is important for manufacturing industries towards achieving in today’s industrial scenario to achieve overall efficiency. The global focus of manufacturing sectors is towards achieving sustainable manufacturing for obtaining ecological and environmental safety. Sustainable machining of components with reduced energy requirement during machining is an essential aspect of economic manufacturing of quality products with environmental friendliness. The consumption of electric power is the major cause that indirectly influences CO2 emissions to the environment. The continuous monitoring of the power consumed during machining will lead towards a greener machining by reducing costs as well as threats to the environment. In this paper, we have carried out a detailed review on the electrical discharge machining (EDM) investigation with a focus on power saving in machining of the metal matrix composites (MMCs) which have a wide application in the field of automotive, space and defence sectors due to higher strength and light weight, low processing cost and having isotropic properties. The review of the literature clearly indicates the need for research to optimize the machining parameters and make the manufacturing activities sustainable. There is a scope for intensive research in sustainable machining of aluminium matrix composites (AMCs) reinforced with nanomaterials with an extended scope of considering environmental aspect with saving in power consumption during machining.
