Ontological Approach to Share Product Design Semantics for an Assembly

摘要

The aim of this paper is to facilitate the transfer of product data semantics from Computer Aided Design (CAD) program to assembly process planning (APP) in product life-cycle. In this paper, an approach to capture, share and transfer assembly design semantic data from SolidWorks (SW) CAD software to assembly device (robot Sony SRX series) is proposed. The proposed approach is based, on its first stage, on defining and extracting assembly design semantics from a CAD model using SolidWorks Application Programmable Interface (SW-API). The second stage of the proposed approach includes sharing and integrating the extracted assembly design semantics with assembly robot device by using three-layer ontology structure. In this layered ontology, different types of ontologies are proposed for each layer: general foundation ontology for the first, domain ontologies for the second and application ontology for the third. Each of these layers aids in defining concepts, relations and properties in assembly design domain and APP domain. Ultimately, the proposed ontology will be used to integrate both domains in product-life cycle.
