ABSTRACT
From past many years lightweight materials like magnesium are enhancing their usage in many applications and industries. This rising need of magnesium inspires many researchers to learn its usage in diverse practices. The present paper investigates the turning of one of the magnesium alloy named AZ91 with SiC at 0%, 1%, and 3%; analyzing different parameters of machining: feed rate, speed of cut. The whole investigation is done with dry machining conditions. For evaluation of turning process three cylindrical bars with three slots were used. The evaluation of process is done by taking surface roughness as the response variable. In this study Taguchi’s L9 orthogonal array with different combinations are used and S/N plots are made and outcomes are analyzed with the help of Analysis of Variance (ANOVA). In results it is analyzed that the important parameter in all tests is feed rate. In addition to this cutting speed were not found to be significant source of variation. Additionally machining at lower feed rates dispersion of surface roughness values in terms of Ra was identified more.
