Abstract Product manufacturing information (PMI) is the most important information in the product digital model. Whether PMI can be clearly and unambiguous represented and exchanged between different computer-aided software (CAx) has become a topic of high interest in current research. To enhance the interoperability of PMI information among different CAx systems and offer framework software to check the PMI realization ability of different computer-aided design (CAD) software packages, this paper proposes a new method for interoperability and conformance checking by establishing a unified PMI ontology. Using web ontology language description logic (OWL2 DL) and semantic web rule language (SRWL), PMI can be described clearly and without ambiguity and can be read and interpreted automatically by the computer. In addition, the ontology also supplies the functions of consistency checking, knowledge inference, and semantic queries. The analysis shows that this ontology has great engineering significance in realization of PMI interoperability exchange and construction of framework software for PMI conformance checking.

一种新的产品制造信息互操作性和一致性检查方法

摘要 产品制造信息（PMI）是产品数字模型中最重要的信息。PMI 能否在不同的计算机辅助软件（CAx）之间清晰无歧义地表示和交换，已成为当前研究的热点。为了增强不同CAx系统之间PMI信息的互操作性，并提供框架软件来检查不同计算机辅助设计（CAD）软件包的PMI实现能力，本文提出了一种通过建立统一的PMI本体来进行互操作性和一致性检查的新方法。 . 使用网络本体语言描述逻辑（OWL2 DL）和语义网络规则语言（SRWL），可以清晰无歧义地描述PMI，并且可以由计算机自动读取和解释。此外，本体还提供一致性检查、知识推理和语义查询的功能。分析表明，该本体对于实现PMI互操作性交换和构建PMI一致性检查框架软件具有重要的工程意义。
