“…Inspired by Fiorentini et al work, Lu et al [48] provided the OWL ontology representation of variational geometric constraint information, and Qin et al [49,50] provided the OWL ontology representation of tolerance zone information and composite tolerance information. In addition to using OWL ontology to achieve tolerance information representation, Zhong et al [76,77] used OWL ontology to study the automatic generation of assembly tolerance types in CAD systems; Ahmed and Han [78] leveraged OWL to implement the exchange of the tolerance information indicated in CAD systems among heterogeneous CAD systems; and Qin et al [79] designed an OWL ontology supported case-based reasoning approach to assist tolerance specification.…”

“…Currently, the representation model used in industry is the EXPRESS model [29][30][31], while at the same time, other representation models, such as surface graph model [32][33][34], representational primitive model [35,36], technologically and topologically related surface (TTRS) model [37], unified modeling language (UML) model [38], extensive markup language (XML) model [39], category theory model [40][41][42][43], GeoSpelling model [44], relationship model [45,46], and ontology-based model [47][48][49][50], have been presented within the academia. The coexistence of different kinds of representation models triggers a series of questions and discussions within the academia and the industry.…”

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.

“…In practice, tolerance modeling not only needs to consider the representation of single tolerance semantics, but also needs to take the representation of composite tolerance semantics into account [25]. To this end, we currently continue the line of research in [22][23][24] and propose a DL ontology-based approach to represent the semantics of composite tolerances. The present paper takes the representation of the semantics of the composite positional tolerance (CPT) for patterns of holes (POHs) as an example to illustrate the proposed approach.…”

“…To tackle such challenge, we have introduced the technology of description logic (DL) ontology in the field of the Semantic Web into tolerance semantic representation and presented a DL ontology-based approach to represent the semantics of the type [22], resultant tolerance zone [23], and variational geometry [24] of a single tolerance. As the benefits of DL ontology, such semantics were represented explicitly and expected to be exchanged automatically among heterogeneous CAD/CAM systems.…”

Explicitly representing the semantics of composite positional tolerance for patterns of holes

Representing the semantics of the interaction of two or more tolerances (i.e., composite tolerance) explicitly to make them computer-understandable is currently a challenging task in computer-aided tolerancing (CAT). We have proposed a description logic (DL) ontology-based approach to complete this task recently. In this paper, the representation of the semantics of the composite positional tolerance (CPT) for patterns of holes (POHs) is used as an example to illustrate the proposed approach. This representation mainly includes representing the structure knowledge of the CPT for POHs in DL terminological axioms; expressing the constraint knowledge with Horn rules; and describing the individual knowledge using DL assertional axioms. By implementing the representation with the web ontology language (OWL) and the semantic web rule language (SWRL), a CPT ontology is developed. This ontology has explicitly computerunderstandable semantics due to the logic-based semantics of OWL and SWRL. As is illustrated by an engineering example, such semantics makes it possible to automatically check the consistency, reason out the new knowledge, and implement the semantic interoperability of CPT information. Benefiting from this, the ontology provides a semantic enrichment model for the CPT information extracted from CAD/ CAM systems.

Model‐based definition (MBD) containing all product and manufacturing information (PMI) has become the data source of future product development because of its incomparable advantages over traditional two‐dimensional drawings. In the whole life cycle of product development, it is an urgent problem to realize the sharing of geometric tolerance specification information of PMI among different CAx (CAD, CAE, CAM, etc.) and the automatic interpretation of its semantics by computer. In this paper, the semantic representation ontology of pattern and combined geometrical specification is studied based on the new generation GPS theory and the construction process is introduced in detail through an example. Benefiting from the logic‐based semantics of the web ontology language (OWL) and semantic web rule language (SWRL), the pattern and combined geometrical specification semantic can be interpreted directly by computer and has the advantages of clear, unambiguous, and consistent at different stages of the product life cycle. At the same time, it can automatically check the consistency of knowledge, reason new knowledge, and semantic query.
