摘要
结合某厂实际,对特征技术作了深入的研究,给出了该厂回转类零件(轴、轮、盘、套)的形状特征分类,建造了特征库,提出用形状特征二叉树构造零件形状模型的方法,进而给出了基于特征的回转类零件模型。在此模型的基础上开发了回转类零件的基于特征的CAD系统,通过STEP格式文件交换,实现了该厂回转类零件的CAD/CAM集成。
In this paper a taxonomy of features of rotational parts is discussed and a model of it is presented.A features library is also established and a binary-tree data structure is used to construct the form model.As an implementation,a feature-based CAD prototype system is developed and integrated with a CAM system through STEPexchange format file.
