This analysis is essential inthe process of obtaining the functional dimensioning of each component thatmeets the geometric requirements set by the specifications.The method is derived from knowledge of the nominal models of each componentand the whole assembly. The first phase of functional dimensioning is basedon the analysis of the positioning of each part in any possible operating state. Thepart positioning depends on the identification and definition of the contact surfacesand their order of preponderance. This method makes it possible to obtainthe dimensioning of the contact surfaces by means of position specifications. Inaddition, by precisely defining the part positioning, the ISO dimensioning can becarried out in such a way that the consistency of the dimensioning with the requirementscan be easily verified.Every functional requirement will generate a tolerance stackup of influencing dimensionsthat must be recorded. Considering that an assembly or device mayhave several operating states, parts may have several operating positions whichshall be analyzed and provide different dimension tolerance stackups and functionaldimensions.For the above reasons, the method must use the language common to all theseenvironments, which is none other than the ISO-GPS language.
