Unformatted text preview: clearance or interference to predefined classes such as clearance fits, transition fits and interference fits. In the case of clearances, they are also labelled as Functional Requirements and are the result of the analysis process. Again, they are expressed as six components torsors but appear on the left side member of the matrix equation in the Jacobian-torsor model (equation 2). They are generally specified on the assembly drawings between two planar faces on different parts and indicate the minimum and maximum values of the admissible play. Conversely, at the part level, the designer specifies tolerances. These are naturally converted into six component torsors expressing the corresponding tolerance zones as internal pairs and labelled as “Functional Elements” in the Jacobian-torsor model. The expression of tolerance requirements is naturally governed by standards such as those of the ASME or ISO. Overall, design driven uncertainties define, in the virtual world, the characteri...
