基于UML模具网络化制造任务信息建模

摘要

模具产品快速开发的能力和对市场的响应速度已成为当前模具制造企业能否生存与发展的决定性因素,模具制造采用网络化的制造模式,能够快速响应客户及市场需求,提升企业的信息化水平,同时有效的缩短产品开发周期,降低生产成本.在对网络制造环境下模具制造任务分解与任务信息构成分析以及模具制造企业综合制造能力剖析的基础上,利用UML面向对象的统一建模语言,建立了模具制造任务与企业综合制造能力的信息模型,给出了它们与此相对应的对象关系数据库模型,实现了制造任务和资源的信息模型到关系数据库模型的转换.%Large diameter Fresnel lens is widely used in solar power station,the DLP projection display and other fields ,yet the mould processing manufacturing is difficultA imed at the machining equipment for large diameter Fresnel lens mold and development of the machining technology, deep analysis is made and study status for machining the lens molds is summarized as well as the development direction in the future is prospected.
