基于面向对象的零件信息模型描述方法的探讨

Approach to object-oriented based descriptive method for information model of parts

分析 ＣＡＰＰ系统的数据结构和数据类型的复杂性，采用面向对象的方法组织 ＣＡＰＰ系统的数据结构。运用 Ｃ＋＋语言作为零件信息模型的工作语言，以阶梯轴的形状特征为例，讨论基于面向对象的零件信息模型的数据结构的实现。

Analyses the complex data structure and complicated data type of CAPP,and adopts the object-oriented way to organize the data structure of CaPP,and applys C++ Programming Language as the working language of part information model .This paper discusses the implementation of the data structure of the object-oriented-based part information model using the shape feature of stepped shaft as an example.
