This paper presents application of taguchi optimization method for simultaneous minimization of burr height and burr thickness influenced by cutting conditions and drill geometry the approach of taguchi design for multi-objective optimization problem is based on the introduction of a new concept of fitness function for. The taguchi method is an efficient approach for optimizing a single quality response in practice, however, most products/processes have more than one quality response of main interest recently, the. Two-step taguchi's dynamic analysis 41 optimization of control factors in the two-step optimization of the current larger-the-better dynamic problem, the quality is first optimized by identifying the control factors which significantly influence the s/n ratio and the sensitivity, and then appropriate control. Orthogonal arrays (oa) provide a set of well balanced (minimum) experiments and dr taguchi's signal-to-noise ratios (s/n), which are log functions of desired output, serve as objective functions for optimization, help in data analysis and prediction of optimum results taguchi method treats optimization problems in two.

Taguchi method is a well known fraction factorial design, which requires minimum number of trials for identifying optimum parametric combination in real time problemsin this paper an attempt is made to review the literatures of various methods used by researchers for multi - objective optimization problems using taguchi. This research proposes a simple, yet very effective, approach for solving the multi -response problem in the taguchi method each quality response is transformed into signal-to-noise (s/n) ratio the average s/n ratio is calculated for each factor level, and then weighted with respect to the level of the largest average s/n. Summary one of the conventional approaches used in off-line quality control is the taguchi method however, most previous taguchi method applications have only dealt with a single-response problem and the multi-response problem has received only limited attention the theoretical analysis in this study reveals.
