As one of major methods to meet information integration of numerical control machines in workshop, DNC (Direct Numerical Control or Distributed Numerical Control) oriented networked manufacturing (Web-DNC system) differs dramatically from conventional ones by having: (1) concurrently supporting networked manufacturing; (2) sharing the numerical control machines via network; (3) optimizing the configuration and reorganization of numerical control resources. This paper deals with the key technologies of Web-DNC system, including: the implementing architecture model with four layers (user layer, service layer, agent layer and facility layer) and the topology architecture. The BL2000 SCM is selected as a COM server to meet the required capabilities of DNC controller. Compared with the communication architecture with fieldbus, a simpler function model of DNC communication technology based on Ethernet technology is presented. A Web-DNC system prototype is developed and proved to be effective in information integration of numerical control machines in injecton workshop.
