Sensitive factor for position tolerance.

A tolerance sensitivity study evaluates the influence of each component tolerance on the assembly tolerance. It is crucial to the improvement to tolerance design. This paper discusses a difficulty in evaluating the sensitive factors of some geometric tolerances (e.g. the position tolerance), due to their connections with a random orientation angle α. An average sensitive factor over α is proposed for the position tolerance. The usefulness of the average sensitive factor is demonstrated through a mechanical example. [ABSTRACT FROM AUTHOR]
