The quality of the interfaces between parts ensures the assembly requirements of a mechanism and the right positioning of functional surfaces. When defining a mechanism, a designer analyzes the failures generated by the geometrical defects of the junction surfaces between the parts. To formalize the design intents clearly, the method proposed, named TLIC, uses positioning tables of the parts to clearly indicate the set up surfaces associated as features and the preponderance order of the features. The requirements of assembly between parts and the tolerancing of the interfaces can then be generated automatically by defining the reference systems.
