Unformatted text preview: ements torsor components corresponding to the specified domain. Thus a domain is a "torsor view" of a given zone. In the other way, we can compute [Samper et al. 2006] a zone from the domain definition. In the general case, the bijection is not true, thus we add a fitting criterion (the smallest, nearest or biggest zone). 3. USE RATE DEFINITION Use Rate (UR) is a dimensionless limiting criterion. It allows to input functional limits in the tolerancing process. UR is used as a metric and corresponds to the inverse of the safety factor. As the allowable displacements of the surfaces are limited by a technological criterion, we characterise the UR concept by a dimensionless number that ranges from 0 to 1. This UR can be a limiting label for either joints or for parts. That is to say that UR can be used for limiting displacements of deviations in parts or for limiting clearances in joints. When UR equals 0 then forces are nil and when UR equals 1 then the object is at its limit. In a tolerancing simulation, UR can be higher than...
