experiment by Taguchi technique. The test samples were taken by varying the particle size
of reinforced SiC as 0.22 µm, 0.106 µm, 0.053 µm, with percentage by weight 5%, 10% and
20%. An orthogonal array and the analysis of variance were employed to investigate the
influence of process parameters on tensile strength. The observed results of orthogonal
array, Analysis of Variance (ANOVA), interaction can be verified by confirmation test.
