CIMS下零件信息模型的研究

Research on the Part Information Model in CIMS

零件是产品设计、制造和管理的基本单元．包含零件生命周期的信息模型是ＣＩＭＳ信息集成、敏捷制造和电子商务的基础，是ＣＩＭＳ在数据库级实现信息集成必须解决的问题．本文讨论了基于特征的包括零件生命周期信息的模型结构，进一步讨论了管理特征、技术特征、材料特征、形状特征和精度特征，以及这些特征的属性组和指针．

The part is a basic unit of product design, manufacture and management. The information model included the part life cycle is base of CIMS information integration, agility manufacturing and electronic commerce,and is a problem that must be solved for CIMS achieving information integration on database level.The model structure included the part life cycle basing on feature is discussed,and management feature, technology feature, material feature, shape feature, precision feature, those feature's attribute group and its index are discussed farther.
