印刷机典型零件特征信息建模方法研究

Research on Feature Modeling of The Typical Parts of Printing Press

特征信息模型是面向整个设计和加工过程,有利于信息在集成系统中流通的建模方法。论述了特征信息模型的构建方法,针对印刷机典型零件的特点建立一个几何信息与工艺信息一体化的特征信息模型,通过零件信息模型层次结构的实例化来实现实例特征信息的描述。较好地解决了CAD/CAPP系统特征信息模型建立与数据共享问题。

The feature modeling is a method for the entire proess of design and processing which makes information flows smoothly among the intgrated system.In this paper,Geometric feature combined with proess feature to describe parts is a better way to achieve the information modelingand data sharing for the charactristics of the typical parts of printing press.
