Optimization of external roller burnishing process on magnesium silicon carbide metal matrix composite using response surface methodology

This paper deals with the optimization of external roller burnishing operation using a CNC lathe for Mg-SiC metal matrix. Magnesium was alloyed 10% (w/w) SiC particles as reinforcement. The Stir casting process used to cast bars. turning then performed on these bars prepare them process. parameters considered during are speed, feed rate, force and number tool passes. Surface roughness, microhardness out roundness were outputs each experiment. Taguchi methodology design an yielded L16 (44) Matrix. Response Methodology procuring optimized set parameters. plots studied understand impact all potential combinations Regression equations formulated between input output optimum surface roughness 0.1506 ?m, hardness 57.9996 HV 0.0151 mm obtained from following parameters: speed of171 rpm, rate 0.18 mm/rev, 21 N 3 found desirability factor 0.9991.
