摘要
产品信息建模是实现现代制造系统信息集成的基础。本文探讨基于ＳＴＥＰ的特征造型ＣＡＤ／ＣＡＭ系统的实现技术和开发方法，以Ｓｏｌｉｄｗｏｒｋｓ９７系统作为支撑软件，用ＳＴＥＰ作为产品信息表达与数据交换机制，研制了特征造型信息描述模式、ＳＴＥＰ的前置处理器和后置处理器。根据应用协议生成ＳＴＥＰ中性文件，完成ＣＡＤ、ＣＡＰＰ、ＣＡＭ系统之间的信息交换与共享。
The product information modeling is foundation for modern mechanical systems to realize information integration The paper studies implementation technology and developing method of the feature modeling system based on STEP It uses the Solidworks 97 system and adopts STEP as its mechanism to exchange product information The information description of feature modeling,the STEP preprocessor and base_processor were developed According to the application protocol,the features in the model are sent to STEP neutral files and the information exchange and share among CAD,CAPP and CAM are attained
