【摘要】 特征技术是CAD/CAM集成的关键,也是产品建模技术的核心。特征模型使CAD、CAPP、CAM等系统共享统一的产品数据模型成为可能。介绍了特征的概念与分类,并以回转体类零件为例,较为详细地阐述了特征模型的总体结构和各类特征模型的数据结构。更多还原

【Abstract】 Feature technique is not only the key of the integration of CAD/CAM system,but also the core of the product modeling technique. Feature model makes it possible that CAD, CAPP and CAM system can share the unique product data model. This paper introduces the concept and classification of the feature, expatiates the whole structure of feature model and the data structure of all kinds of feature models to rotational parts.更多还原
