| 摘 要： | 针对并行工程的需求，基于广义特征和ＳＴＥＰ标准建立了零件信息模型，并在Ｐｒｏ／Ｅｎｇｉｎｅｅｒ软件二次开发的基础上，实现了一个基于特征的ＣＡＤ系统，该系统可实现自动特征识别。基于所建立的零件信息模型，系统可自动生成ＳＴＥＰ文件，为设计的后续过程提供丰富的零件信息，便于实现ＣＡＤ与后续过程的集成和并行。利用建立的零件信息模型，实现了ＣＡＤ／ＣＡＰＰ／ＤＦＭ的信息集成。

| Abstract: | A part information model is established based on STEP and generalized feature according to concurrent engineering. A feature-based CAD system is developed based on Pro/Engineer software. The features of a part is recognized automatically by means of this CAD system, and STEP file is generated based on part information model in order to provide rich part information for down-stream activities. The information integration of CAD/CAPP/DFM is implemented based on the part information model. |
