Unformatted text preview: 10 years, a lot of academic researches point out the link between functions and specifications [Dantan et al., 2003], [Dufaure et al., 2003]. Functional Analysis, early in the design activities, allows to better analyze the relation between physics of functioning and tolerances. The functional requirements have to be translated into geometric requirements on parts and assembly. Tolerance specification must also take into account data coming from process analysis. Process analysis points out the setting of machines on the shop floor. The dimensional and geometrical variations are analyzed for actions on the machines and also for the feed back to the tolerance analysis activity. The assembly sequence, manufacturing plan and the variations of each process are useful. In particular the link between Statistical Process Control and tolerance specification has to be improved to access statistical data. Tolerance Analysis is totally based on the models used for tolerance specification [Guilford...
