Development of Communication System in Numerical Control Workshop Based on Ethernet

Numerical controlled workshop has 10 sets of CNC equipment and CAD/CAPP/CAM center, the problem is how to implement information management. This paper applied ZNE-100TL module to realize the Ethernet hardware connection. Through software development, Numerical controlled workshop has completed communication the CNC equipment with CAD/CAPP/CAM center, which provides a convenient for production management and data transmission in numerical controlled workshop.
