Abstract：

According to the characteristic of sheet-metal products, Sheet-Metal CAD/DFM Prototype System based on Pro/E is established by feature technology on the basis of feature modeling.This system realizes the application of DFM in the field of sheet-metal machining and the share and integration of design and manufacture information in product life cycle.This paper introduces framework, principle of design and key technologies adopted in this system.The module of manufacturing capability evaluation is also described.STEP is considered as a source file describing the data information of product design.The medium for obtaining and passing product information is the database including design and manufacture features of products.By STEP file and product database, integration of CAD and DFM is truly realized.The evaluation results show that DFM can greatly reduce product cost, improve production efficiency and accelerate the marketing speed of new products.
