Optimization for Turning Metal Matrix Composites with Multiple Performance Characteristics

Abstract

In this paper, an optimization technique for turning metal matrix composites (MMCs) is proposed using the Taguchi method with multiple performance characteristics. The orthogonal array, multi-response signal to noise (S/N) ratio and analysis of variance (ANOVA) are employed to study the performance characteristics. The cutting parameters (cutting velocity and feed) and cutting time are optimized with consideration of multiple performance characteristics including tool wear, surface roughness and the power required to perform the machining operation. The results showed that cutting time was the dominant variable on multiple cutting performance characteristics. Confirmation tests of the optimal levels with the initial cutting parameters are carried out in order to illustrate the effectiveness of this method in turning metal matrix composite.
