Optimization of turning operations with multiple performance characteristics

Abstract The optimization of turning operations based on the Taguchi method with multiple performance characteristics is proposed in this paper. The orthogonal array, multi-response signal-to-noise ratio, and analysis of variance are employed to study the performance characteristics in turning operations. Three cutting parameters namely, cutting speed, feed rate, and depth of cut, are optimized with considerations of multiple performance characteristics including tool life, cutting force, and surface finish. Experimental results are provided to illustrate the effectiveness of this approach.
