A Review on Taguchis Technique of forming Orthogonal Arrays

K. L. N Murthy;B Sandeep, Ramakrishna Vanukuru, T Krishna Chaitanya


Prediction and utilization of right parameters in any fabricating process is the first and foremost step that is essential to maintain the quality of any fabricated product. Quality of fabricated commodities by the industrialists should not be a drawback, instead that should be a main asset for the development of any industry. General algorithm, artificial neural networks, trial and error method, Design of Experimentation (DOE) are some of the optimizing techniques applied in the fabrication processes, among which DOE method framing orthogonal arrays proposed by Dr. Genechi Taguchi is the simplest and widely executed quality control technique. Maintaining the quality without creating loss to the society is the primary motto of this methodology. According to him, consistency of performance of a product means showing its standard, and inconsistency means lack of its quality. Taguchi‟s approach of quality control using „parameter design phase‟ of three quality engineering activities such as parameter phase, tolerance phase and design phase not only minimizes the number of experiments to be conducted but also reduces the time, expenditure and in the end, it gives us a set of appropriate parameters that are desired during final fabrication of products. The present paper speaks about the steps that are to be followed for selection of number of parameters and number of level for forming orthogonal arrays.
