| Research Abstract |
The manufacturing industry is increasingly dependent on digital tools, such as CAD, CAE, CAM, product data management (PDM) systems CNC machines to design and manufacture products. Moreover, the movement toward concurrent engineering drives the need for frequent transformation of the product data between different digital tools. In order to realize the articulate link between design and manufacturing and the traceable manufacturing system, it is necessary to realize interoperable digital tools which represent the semantics of information independently of any implementations. Interoperability characterizes the ability of product model data to accurately represent objects in all collaborative engineering environments. Today, all engineering data, such as geometry representation data, tolerance data, etc., are not used throughout product development processes. An interoperability error makes product model data unusable when applying digital tools. If an interoperability error arises in co

llaborative engineering applications, tracking the error back to its source is expensive (if not impossible) and requires a significant amount of time. Moreover, the quality of data that represent information should be ensured during the product life cycle. In this research, the Digital Semantic Model that fulfills the above requirements was proposed.
The digital semantic product model consisted of the quality assurance of the product model data, the semantic modeling for humans (such as designer and worker), understandable and computer readable data, and the functional modeling for supporting the product life cycle. In order to ensure the product model data, the Product Data Quality Checking method for the ISO Standard product model was proposed. In order to support all of the product lifecycle activities, the functional model for each activity was developed based on the related ISO Standard. In order to represent the semantics of the data, the EXPRESS language for data modeling and XML for representing the data, was adopted. Less
