Optimization of Process Parameters in turning of Hybrid Metal Matrix Composite using Response surface Methodology

Abstract

Metal matrix composites consisting of two or more physically/chemically distinct phases are potential material
for aerospace, automobile, defense, sport and research industries. Aluminium matrix composites reinforced with ceramic
materials such as SiC, TiO2, Al2O3 etc is attractive material for modern industrial sectors consequent to the increasing
demand for new light weight materials having greater mechanical strength. Such materials are termed as hybrid aluminium
matrix composites (HAMCs). The present investigation is to find the optimum machining parameter of CNC turning centre on
Al-HMMC. The main objective is to find the optimum cutting parameters to achieve low value of surface roughness and high
material removal rate. The mathematical models have been proposed for modeling analysis of the effect of turning parameter
on the performance through response surface methodology (RSM). A central composite design involving three process
parameters i.e speed, feed and depth of cut has been employed to establish a mathematical model between the process
parameters and responses.
