Abstract :
This paper presents the application of WLAN (Wireless Local Area Network) in networked DNC system. The networked DNC System has been built based on WLAN, and it mainly consists in computer, NC machine with RS232 interface, Network Interface Card as well as Wireless NIC. NC machine with RS232 interface is controlled by computer based on WLAN communication technology, and the Network Interface Card as well as Wireless NIC play an important role in communication between computer and NC machine, the key technology, including WLAN, networked DNC integration, communications protocol conversion and network wiring have been analyzed, and the test system for wireless channel performance, data transfer rate and response time has been set up. The results show that the WLAN network technology in DNC integration can meet the needs of manufacture automation in workshop, and based on this technology, the level of automation in CNC equipment has been greatly improved.
