【摘要】 传统的切割方式效率低下、工作环境恶劣。本文首先通过对虚拟制造技术的分析，提出了基于激光切割的虚拟制造系统LCVMS；其次，在对系统的功能性进行详细分析的基础上，建立了系统的基于J2EE平台的三层分布式体系结构，依次是客户层、EJB层、数据层；再次，对应于系统体系结构的各个逻辑层，采用组件化的技术将系统的功能组件化，并设计了系统各功能组件的部署方案。具体讲：客户层包括两个用户界面组件，一个切割图形的编辑界面组件，一个系统管理员的管理界面组件；EJB层是系统的核心功能集，采用了J2EE平台的分布式组件技术EJB，包括一个切割路径优化的组件、一个数控代码自动生成的组件、三个对后台数据库进行访问的实体EJB组件；数据层是系统资源的持久存储，包括一个会员资料信息的表、一个系统使用信息的表、一个系统工艺参数的表。最后，在分别对每一个组件的功能进行描述的基础上，采用软件工程里的对象建模技术UML详细设计了每一个组件。更多还原

【Abstract】 The efficiency of traditional cutting mode is very lower. Firstly, this article analyze the characters of virtual manufacturing technology and bring forward a virtual manufacturing system based on laser cutting CVMS; secondly, on the basis of the analysis of the system function , we build a three-layers distributed architecture that is composed of client layer, EJB layer, data layer of the data layer of the system based J2EE platform. Thirdly, we use component model technology to break the sytem into components according to the logic layers of the architecture of the system, moreover we design the deployment . Particularly speaking , the client layer is composed of two user interface component, one is edit interface component of cutting graphics, the other is a administrator interface component; EJB layer EJB layer is the core function component, which use the distributed component technology EJB and is composed of a cutting path optimization component, a NC codes generation component and three EJB entity component that access end point database; data layer is a persistent system resources, which is composed of a members information table , a statistic information table about system and a technologic parameters of a members information table , a statistic information table about system and a technologic parameters table. At last, on the basis analysis of every component’s function, we use object modeling technology UML to design every component in details.更多还原
