3D Manufacturing Feature Based Integrated Information Model and its Modeling System Development Based on XML and NX Platform
With the development of CAD/CAM technology,the key to CAD/CAM integration consists in constructing a common product model.In the paper,shaft parts are taken as research objects.Interactive feature-based modeling method is adopted to avoid complex algorithms for feature recognition.The functional framework of the system developed is put forward.3D geometric model is used as the core to integrate all manufacturing feature data of a part.All related manufacturing data are organized in a feature model and stored in a XML file.The 3D geometric model and corresponding feature XML file constitute an integrated information model for the part.In the modeling process,information consistency examination is carded out to check the feature model and judge whether a feature in the feature model should be modified.The system has already been used to realize a 3D CAD/CAPP.
