Modeling and implementation of Digital Semantic Models for 5-axis machining application

In order to realize the articulate link between design and manufacturing and a traceable manufacturing system, it is necessary to represent the semantics of information independently of any implementations. Moreover, the quality of data that represent information should be ensured during the product life cycle. A significant amount of research for machining process planning and machining feature extraction has been carried out to help realize an integrated CAD/CAPP/CAM system. However, all data are not used throughout product development processes. The standard for the exchange of product model data (STEP) has also emerged as a viable method for product model data exchange among design activities. However, a consistent application for integrating design, process planning and machining for mechanical components based on STEP/AP set has not completely been developed thus far. In this research, the digital semantic model that fulfills the above requirements is proposed. In this paper, modeling and implementation of digital semantic model for 5-axis machining is reported
