OPTIMIZATION TECHNIQUES OF TURNING PARAMETERS OF IN-SITU METAL MATRIX COMPOSITE FOR SURFACE ROUGHNESS USING TAGUCHI METHOD
Keywords:
In-situ composites, surface roughness, L27 (313) orthogonal arrayAbstract
In-situ metal matrix composites have a potential for structural applications because of the presence of fine, small size and uniform distribution of reinforcements. An in-situ synthesized reinforcement particle yields better interface strength between the matrix and reinforcement than the composites fabricated by ex-situ technology. As a result, the mechanical properties, such as strength, stiffness and creep resistance are improved. The objective of the paper is to analyze the influence of machining parameters on surface roughness in turning of in-situ metal matrix composite using taguchi method. The experiments are carried out by using L27 (313) orthogonal array. Analysis of variance (ANOVA) is carried out to identify significant machining parameter affecting the surface roughness. The result indicates that cutting speed is more significant parameter than others. In order to correlate process parameters and measured surface roughness, a mathematical model has been developed by regression analysis.
