摘要
针对数控机床轴承的全生命周期数据管理缺少统一模型的问题,分析了数控机床轴承全生命周期数据关系和集成管理需求,建立了全生命周期数据管理模式;应用多维度建模方法,从数据属性、数据结构、组织约束和操作机制等方面构建了轴承集成设计、制造和运行维护三个阶段的多维度数据模型,并结合实例应用,设计了数控机床轴承全生命数据管理系统,实现了预期效果,为实现数控机床轴承全生命周期数据集成管理系统研发奠定了理论基础。
In view of a unified mode absent of the CNC machine bearing life-cycle date management,the demands for data relationships and integrated management of the CNC machine bearing life？cycle were analyzed herein,and the life-cycle data management mode was established.Using the method of multidimensional modeling,three stages of multidimensional data model about the bearings integrated design,manufacturing and operations were set up from aspects of data attributes,data structure,organizational constraints and the operation mechanism.Combined with the application examples,the CNC machine bearing life data management system was designed and the expected effectivenesses were achieved,which lays a theoretical foundation for data integration management of lifecycle of the CNC machine bearings.
