Dnc System Based On The Automatic Answering Server Components

With the progress of numerical control technology, more and more numerical control (NO equipments are used, then the use and management of these equipments become urgent problems. The technology of distributed numerical control (DNC) which can solve the problems comes into being with the development of computer technology, communication technology and manufacture technology. In traditional DNC systems, computers are often placed near machines in order to control NC program transmission easily, but this usually result in a bad environment and inconvenience of computer using, greatness of investment, difficulty of management of NC program, etc. And also it is difficult to upgrade the DNC system.The technology of DNC is introduced firstly in this article, and a new type of DNC system, which bases on auto-respond server and component object mode technology, is bring forward to solve the above problems. Then, the frame structure of the DNC system is given based on the research of the related technology, and many key technologies of the auto-respond server are researched. Also, the design, experiment and application of the server are introduced. The DNC system developed solves the problems faced at traditional DNC, and meets the current needs of Agile Manufacturing on DNC system.
