A Comparison of Central composite design and Modified Taguchi approach to optimize the process parameters

Abstract

Second order rotatable design (SORD) concepts will be more useful in developing the appropriate empirical relations. As the number of input variables are increasing (with the assigned levels to each variable), there is a need to conduct more number of experiments which may sometimes be practically impossible. Taguchi designs can solve the problem with less number of experiments and provides complete information useful for the applications of second order rotatable designs. This article provides a comparison of Central composite design and modified Taguchi approach and its validation by tracing the optimum process parameter on the experimental design. It is possible to get the required information and the expected range of process parameters from modified Taguchi design.
