PDM and ERP integration methodology using digital manufacturing to support global manufacturing 总被引:1,自引:1,他引:0

Global manufacturing companies must implement manufacturing engineering with proper consideration given to the manufacturing process and resources that are appropriate for the particularities of each manufacturing site. Particularly for effective enterprise resource planning (ERP) system implementation under a global manufacturing environment, the product data management (PDM) integration for product data is one of the important keys to success. For such product data integration, engineering bill of materials (EBOM) needs to be transformed to manufacturing bill of materials (MBOM), but the MBOM transformation must be done in such a way as to fit the particularities of each manufacturing site. In this process, a methodology appropriate for integration and transformation is required. This paper proposes digital manufacturing as the key tool of data integration between PDM and ERP. Digital manufacturing, as a technology possessing the physical and logical computer modeling and simulation technique for actual manufacturing, provides the methodology for transforming EBOM to MBOM that fits the particularities of each manufacturing site, based on the process and resource models which reflect the particularities of each manufacturing site. It also provides the methodology for MBOM verification and the process and resource model integration. Using such method, the MBOM and the process and resource data, verified and appropriate for each manufacturing site, can be sent to the ERP system. 相似文献

In order to stay competitive with international markets, companies must deliver new products with higher quality in a shorter time with a broader variety of versions at minimum costs. Virtual manufacturing (VM) is quickly becoming an interesting strategy for product development. Primarily aimed at reducing the lead times to market and costs associated with new product development, VM offers a test-bed for the time-consuming and expensive physical experimentation. In this paper, several key issues for developing a virtual turning test-bed by using virtual manufacturing technology are discussed, i.e., representation of a workpiece with the capability of transferring error data used for machining accuracy prediction and reflecting the machining accuracy, representation of the swept volume of a tool for simulating turning process with high efficiency. The construction of surface topography, a basic model for machining accuracy prediction is also highlighted. The representations and relevant algorithms discussed in this paper are implemented in a virtual turning test-bed. A virtual machining and inspection system (VMIS) for ultra-precision diamond turning is presented and experiments are carried out to demonstrate it. 相似文献
