面向工艺设计的回转体零件特征信息描述模型研究

Study on a Feature Description Modelingof the Rotational Part Directied at Process Design

零件信息的描述决定着CAPP系统的数据结构及其实现,面向工艺设计的回转体零件信息描述模型,采用了尺寸类结构,同时,引入了以基准来描述特征间的拓扑关系的概念,从而有效地实现了对于回转体信息的描述。

It is of great significance to carry out research on description of a part as such a step determines the data structure and process implementation of the CAPP system. This paper presents a feature description modeling of the rotational part directed at process design. This modeling describes the shape of the part based on its features, the dimension of each features based on interior and exterior references, which effectively fulfils the task of the description of information of the rotational part.
