ELECTRICAL DISCHARGE MACHINING TRAITS OF ALUMINIUM METAL MATRIX COMPOSITES - A EVALUATION

Electrical Discharge Machining (EDM) is the system of machining electrically conductive substances via utilising precisely controlled sparks that arise between an electrode and the work piece within the presence of a dielectric fluid. Aluminium metallic Matrix Composites (AMMC’s) are new iteration engineering substances that possess sophisticated physical and mechanical homes in comparison with non-strengthened alloys. This makes them appealing for wider range of applications in automotive, aerospace and security industries. These substances have fascinating traits equivalent to high strength to weight ratio, high durability and low value of coefficient of thermal stability. It is extremely complex to reduce the elaborate shapes by means of utilising conventional Machining. High device put on and high rate of tooling is also a issue in traditional Machining, Unconventional Machining presents an alternative option to this difficulty. This paper offers a overview of study work done on AMMC’s on EDM, Wire EDM, Powder combined EDM, EDM in Water, Micro EDM. The paper additionally discusses the future traits of study work in the identical subject
