Abstract


Feature modeling technology is the development requirements of advanced manufacturing technology , the establishment of a geometric information that is contained , but also contains process information model is part feature CAD / CAPP / CAM integrated system is one of the key technologies . Feature modeling system can provide the required follow- CAM system information part geometry and process information, to achieve manufacturing resource -oriented design. In this paper, feature-based modeling technology, the structural parts of the structural analysis, the parallel combination of manufacturing and design , proposed a new definition of machining features and machining features using the proposed concept of machining features proposed system architecture , designed specifically for software system. This topic is studied mechanical structure for certain types of electronic project design, machining features based modeling approach that combines a large enterprise manufacturing resources , to take a rapid manufacturing process design methods, the design and manufacturing merger considered together , and thus on the processing characteristics of the new paper -based definition of research needs to done . Proposed based processing constitutes the processing unit of behavior , behavior by the processing unit to express and describe the definition of machining features , thereby machining features to describe parts of the modeling process , the product features and machining features unite to form a new set the feature-based modeling technology . This technique is designed to achieve a combination of information and information processing , greatly reducing the mechanical product development and design cycles. In this study, carried out by VB software interface program development , combined with PROE software for the graphical display of product modeling , development and design of machining features based part modeling software system , relying on the development of the software system to complete the structure of the product design development, the final generated files directly into CNC machine tools for processing. And completed the six product development, design information and processing to achieve a combination of information , greatly reducing the mechanical product development and design cycles.
