Research Of Virtual Manufacturing System Based Laser Cutting

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.
