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(More)
Ethernet communication isn't used directly in numerical control (NC) system, since its non-deterministic time delays and non-synchronous communication. In this paper, the system architecture of digital interface and the communicating- protocol of digital interface in NC system based on the Ethernet technology are made. The protocol was tested by experiment(More)
The hardware-in-the-loop simulation, which can perform simulation study by placing the needed actual control object in the loop of the simulation system and verify the actual control effect of the control strategy rapidly, is a real-time simulation technology for actual process. In this paper, based on the dSPACE(digital Signal Processing and Control(More)
