Abstract Manufacturing and inspection in model-based engineering, achieving computer-readable and -interpretable tolerance specification representations, and maintaining unambiguous and consistent semantics throughout the life cycle of product design are issues that have attracted the attention of researchers and require urgent actions. An ontology method based on skin tolerance model is proposed in this study to address the abovementioned problems. Tolerance specification semantics described by the GeoSpelling language can be consistent at different stages of product development. In the ontology as a formal shared concept model, the knowledge described by the web ontology language and the semantic web rule language can be read and interpreted automatically via computer. The ontology is based on a rigorous description logic and describes tolerance information with clear and unambiguous semantics. The inference algorithm of this ontology can be used for ontology consistency checking, knowledge reasoning, and semantic query. The proposed method utilizes the advantages of ontology artificial intelligence technology and GeoSpelling language to describe tolerance semantics. Thus, this method is suitable for consistent semantic data exchange in different heterogeneous systems and automatic interpretation of tolerance semantics in smart manufacturing.

1 Introduction Geometric deformation is unavoidable during manufacturing due to the precision error in the process and the uncertainty in the measurement (ISO 2011a). Geometric product specification (GPS) is used to describe the product accuracy * Meifa Huang [email protected] Zhiguo Peng [email protected] Yanru Zhong [email protected] Zhemin Tang [email protected] 1

requirements and control the effects of geometric deformation on the function and quality of mechanical products. Tolerance specification design, assignment, and analysis are the main tasks of tolerance design (Armillotta and Semeraro 2011). Computer-aided tolerance design (CAT) is a computer system for product dimension and tolerance optimization design. A successful CAT system must first be explicitly explained in the technical manual and the tolerance standard, but this condition requires that the tolerance information be a clearly unambiguous, computer-readable, and -interpretable representation (Qin et al. 2018).
