“…Considering the representation of design requirements is very important for tolerance information representation, because both tolerancing and assembly serve the purpose of fulfilling the function requirements of products. Even though some single tolerancing cases (e.g., the tolerancing cases presented by Ballu and Mathieu [89], Wang et al [90], Anselmetti [91], Armillotta [92], and Cao et al [93]) have involved it, systematically considering design requirements in tolerancing remains a challenging objective.…”

A good representation model of tolerance information is indispensable for achieving computer-aided tolerancing. Currently, the representation model used in industry is the EXPRESS model, while at the same time, a number of other kinds of representation models have been presented within the academia. The coexistence of different kinds of representation models generates a series of questions and discussions: can the EXPRESS model completely implement the representation of tolerance information semantics in an explicit, computer-readable, and computer-interpretable way? What challenges have been addressed to date by the presented representation models? What are the advantages and disadvantages of each representation model? What capabilities should an ideal representation model have? What are the potential research directions in tolerance information representation in the future? To approach these questions, a review of representation models of tolerance information is presented in this paper. An in-depth analysis of existing representation models is firstly provided. Then, the review makes a detailed comparison among them based on this analysis. Finally, some future research directions in tolerance information representation are suggested.

“…O propósito do toleranciamento funcional, segundo Anselmetti, (2006), é criar desenhos mecânicos de partes de um mecanismo de maneira a gerar geometrias aceitáveis utilizando um formato normalizado (ASTM, ISO). A base para a definição da funcionalidade de uma peça são seus requisitos funcionais.…”

“…Firstly, the tolerancing analysis was performed by the analysis lines method (8) to detect the impact of geometrical defects and understand the worst cases configurations for the straightness of the shaft maximising the insertion forces. The result of this study is that the straightness is mainly affected by the clearances and the angular deviations on the junctions between the seals supports and the slim parts as shown in Figure 6.…”

The functional tolerancing of hyperstatic mechanisms provides contractual documents established following the ISO tolerancing. The tolerancing methodologies consider that the mechanism is infinitely rigid. These mechanisms impose tight clearances to ensure the functional requirements and parts fittability. The proposed methodology consists in developing a mechanical model relating the tolerances obtained by traditional methods of geometrical tolerancing and the parts deformability to define the tolerance values of the geometrical specifications. The first step is to define the geometrical specifications with ISO tolerancing. The fittability between two parts in contact requires maximum material conditions. The functional requirements employ least material condition. The second step consists in defining the capacity of parts to deform taking the tolerance values into account. A mechanical model is described relating the parts deformability to the tolerances to guaranty the conformity of the functional requirements and assembly parts fittability. As a validation example, the proposed methodology is used on a hyperstatic mechanism composed of two subassemblies: an outer tube and a shaft made of several assembled sections.
