Construction Model And Real-time Technology Of Communication Of Network Numerical Control

The fast-speed development of computer network technology and information technology leads to the ceaseless change of manufacturing,the network numerical control (NNC) -a new technology ,was arisen at the historic moment. After a deep research collection and analyzing of information internal and external on information integration technology,direct numerical control(DNC) interface technology,network technology and computer communication technology,the writer brings to the construction model of NNC and realizes real-time communication of NNC by program,discusses the function of basic information management of NNC.The hardware part of the real-time communication interface includes high performance universal microcomputer,multi-port serial board,adapter and network adapter,realizes the communication of NC took DNC computer or network.The software part of the interface includes basic information management system of NC tool and multiple serial port communication etc . The software is designed under Windows 2000 platform with Microsoft Visual C++ 6.0,it has many advantages such as:friendly interface,easy to use and transmit,etc. So it can be used not only in manufacturing factory,but in teaching and training of the NC machine tools and certainly has the good prospect of application and high utility value.
