Determination of Robust Tolerance on the Lower-level Characteristics

The determination of the tolerance on the lower-level characteristics for the given upper-level characteristics is an indispensable problem in manufacturing industries. The procedure, proposed by Taguchi, for this matter can be easily applied in engineering fields due to its conceptual simplicity. However, the previously developed methods are known to have some limitations in the field applications, because the value of each major factor determining the tolerance cannot be obtained exactly. In this paper, a tolerance design procedure is proposed under the assumption that the major factors to determine the tolerance is uncertain. For the validity of the method proposed in this paper, a hypothetical problem is employed and analyzed.
