The Study Of Network Technology In CAD System About Coldroll Forming

Cold roll forming products has being regarded as a king of economic section steel that received widespread used in architecture, traffic, mechanic and household appliance. But for the reason of the complexity of geometry, kinematics and dynamics during the process of cold roll forming, the geometry nonlinear > physic nonlinear and boundary nonlinear emerged obviously, so the acquirement of technology and data sharing had been conversation carefully.With the development of computer technology, especially with fast development of hardware and software in 21st, Internet has been enter the family as a common thing and had drag the human into epoch of information economy. It has become the focus noticed by all the professions that how to utilize this kind of high speed and convenient communication appliance serve our society.The paper represent the conception and the development of cold roll forming. Internet and database first. Then establish the network program based on Client/Server model by use ASP, construct the expertise knowledge base of empirical data about design of passes , the drawing base and the numerical simulation base be used to loading drawing paper about cold roll passes and result of numerical simulation. It had been made a compact base for virtual processing through combine network and database organically.The paper study the agile manufacture tentatively, except implement remote data sharing ^ remote passes design and remote numerical simulation, it also include integrated information, such as the need information in market and functional parameter of products etc, thus boot the cold roll forming into network, virtualization and agile.The paper has made a compact base for the virtual processing and agilemanufacture about cold rolled forming section.
