Unformatted text preview: The models used within the systems are not clearly presented because it is very difficult to obtain information from CAT system vendors. The authors have distinguished 4 aspects to analyze the CAT systems, tolerance representation, tolerance specification, tolerance analysis and tolerance synthesis. These 4 aspects are not at the same level, the first one refers to how tolerances are represented computer internally, this aspect point out directly on the models used for the description of the mechanism without and with geometric variations. Tolerance specification is an important activity for tolerancing. It tries to answer the question: Which tolerance types and values are needed on features to control functional requirements? Tolerance analysis is a method to verify the values of functional requirements after tolerance specification on each isolated part. This method is totally dependent on the models chosen before. A lot of tools are also generally provided to the designer to understand...
