Examination on Surface Roughness in EDM of Aluminium 6061 Reinforced with 5% SiC Using Design Experiments

Article Preview

Abstract:

This paper presents a prediction and evaluation of surface roughness based on Taguchi’s method and the analysis of variance (ANOVA). The experiments were conducted on aluminium 6061 reinforced with 5% SiC to study the surface roughness under various cutting conditions. The objective was to establish a correlation between current, pulse on time flushing pressure with the surface roughness in the metal matrix composite (MMC). The correlation was obtained by multi-variable linear regression and compared with the experimental results.
