Review on Non Traditional Machining of Metal Matrix Composites

Abstract

Material Science is an everlasting field in engineering world. There is a scope for researchers and scientists to carryout investigation until a last metal is available in the earth. Due to globalisation and technological development there is a necessity to find new combination of materials for specified applications in various fields ranging from Nano scale level to large aerospace industries. A single crystal material cannot be used for all range of applications because of its rigid property and behaviour. This equips the researchers to introduce composite materials instead of isotropic materials. Metal Matrix Composites having special attention among other composites due to flexibility of altering properties which is better substitution for monolithic materials like steel. Since MMCs having hard abrasive particles it is not easy to machine by conventional machining process. The only way to machine MMCs with less or without tool wear, less power consumption is non-traditional machining process. The present review paper focus on the machining of MMCs through non-conventional machining process like EDM, EDD and ECM. Also this paper covers the effect of input process parameters on output responses like Metal Removal Rate (MRR), Tool Wear rate (TWR) and Surface Character. Many authors were used different statistical tools to optimize the process parameters.
