基于特征的航空机载设备壳体类零件CAD系统

A Feature-based CAD System for Housing Parts of Airborne Equipment

为了满足航空机载设备壳体类零件集成制造的需求，建立了基于特征和STEP标准的零件集成信息模型，以此为基础在UG II 平台上利用UG/Open API接口开发了一个基于特征的CAD系统。该系统为制造后续环节提供较完备的零件设计和制造信息，便于实现零件设计、制造、测量的集成。

To meet the needs of integration manufacturing of housing parts of airborne equipment, an integration model is built up based on the part features and STEP standard. With the model, a feature-based CAD system is developed on the UGⅡplatform with the aid of UG/Open API interface to provide more complete information on part design, manufacturing and measuring for the follow-up processing.
