Taguchi Method of Quality Control
Candlefocus EditorTaguchi Method is a systematic approach to product design that employs cost-effective measurements to reduce product variability and production waste. It is based on the premise that determining the variability of a product or process is the key factor in attaining quality. Design of experiments helps to identify and quantify the most significant variables that produce variance, so that the effects of these variables can be minimized.
Taguchi Method uses a highly structured approach to design experiments in two phases: the Parameter Design phase and the Robustness Evaluation phase. In the Parameter Design phase, the input parameters of the production line are determined and manipulated to produce the best combination of these inputs. During the Robustness Evaluation phase, parameters are measured and tested to determine how well the production line responds to changes in input variations. By applying key performance indices such as signal-to-noise ratios, confidence limits, and performance criteria, Taguchi Method can identify optimal settings, reduce variability, and efficiently produce a desired quality level.
Today, Taguchi Method is used in various industries, including automotive, electronics, medical, manufacturing, and pharmaceuticals, among others. Its popularity is due to its emphasis on design over manufacturing, since the process is much less expensive and less time-consuming. The method also helps to minimize defects and make sure that the quality of the end product is consistent, as well as increasing customer satisfaction by ensuring that products meet their intended design specifications.
In summary, Taguchi Method of Quality Control is a cost-effective, systematic approach to product design that seeks to minimize product variability and reduce production waste. By its emphasis on controlling input parameters and measuring the effects of their variations, Taguchi Method allows for efficient and reliable production of quality products. Its popularity is due to its effectiveness in meeting customer needs and its cost-saving advantages. It has been adopted by many of the leading companies in the world, such as Toyota, Ford, Boeing, and Xerox.
