Internet/Ethernet-Based Computer Numerical Control System

With the development of Internet/Ethernet, the computer numerical control system based on Ethernet/Internet has been a subject of much study on e-manufacturing. This paper describes the architecture of computer numerical control system which adopts Internet/Ethernet from higher management level to lower field device level. It defines the information types and the information flow feature, and presents the solutions which include the Web-based remote process, TCP/IP and socket based local process and collision avoidance based real-time communication process. Some experiments were conducted to test the solutions. The results show that the computer numerical control system based on Internet/Ethernet can meet the requirement of the application.
