The importance of quality control within the relationship between the quality engineering and Taguchi methodology

Nowadays there is a strong relationship between the quality control and quality engineering in the modern advanced manufacturing. Quality engineering is an interdisciplinary science which is concerned with not only producing satisfactory products for customers but also reducing the total loss. Quality engineering involves engineering design, process operations, aftersales services, economics and statistics. Although the Taguchi Robust Design is the first concept comes to mind when thinking of quality engineering, the definition of this major has been used in different manners in the literature. There are also differences on the definition of the quality which has been made by experts. The aim of this study is to contribute to the literature to avoid deviations on definition of the concept of Quality Engineering, which has not been defined yet by ISO - International Organization for Standardization. This study pointed out that the process of quality control is a part of on-line quality engineering rather than off-line phase and tries to ensure planned and/or improved values are satisfied during mass production. © (2015) Trans Tech Publications, Switzerland.
