基于STEP的CAx信息管理与系统集成的研究

结合制造业实施CIMS的整体设计要求，提出了基于STEP集成技术设计新型CAx信息管理与集成系统（CAx-IMIS)的基本构架，全面分析了这一系统应具备的基本功能，以Pro/E工具软件为基础，建立、管理零件信息模型，基于SDAI生成STEP中性文件实现数据交换的基本思路，探讨了在产品全生命周期内产品数据在CAx系统间的交换与共享。

Study on CAx Information Management and Integrated System Based on STEP

A new framework for the design of a CAx information management and integrated system (CAx\|IMIS) based on STEP integration technologies is proposed in this paper according to the design requirements of computer integrated manufacturing system. It uses the Pro/E system to generate and manage the part model based on the feature information .The basic idea of realizing data exchange through STEP neutral file which is generated by using SDAI is illustrated. It discussed the transfer of whole life product data in the CAx system.
