NON-CONVENTIONAL MACHINING OF ALUMINIUM METAL MATRIX COMPOSITE

Aluminium metal matrix composite is slowly making in roads into various engineering applications. Among the limitations of this material is its difficulty to machine due to its soft and particles tend to wrap around tool bit and break the tool. This material has yet to be tested using non-conventional machining techniques such as. This research explores the possibility of machining using Electro-discharge machining by varying various machining parameters. Results indicated that aluminium metal matrix composite can be effectively EDM machined at low peak current at certain ON-time and OFF-time
