构造机械零件的概念化参数模型

从机械零件三维设计的角度出发，利用特征造型的技术，提出了构造概念化参数模型的思想和方法，以轴类零件为例，分析和探讨了特征的分类、定义及模型建立的一般技术。

Based on the feature construction technology, the authors presents the ideals and methods of conceptual parametrical model from 3D -design point of view. Using shaft as a demonstration, the authors analyze and discuss the definition and classification of features, common technology of constructing models, and the result of this method.
