Research And Design Of DNC Communication And Management System For NC Machine Tools

With the rapid development of computer and Internet technology,integrated manufacturing system,the trend of network is also more prominent,effectively improve the competitiveness of enterprises.And the CNC machine tool group has high concentration,low investment cost,the characteristics of significant effect,for enterprises to realize the integration of CAM CAD/ is of great significance.Therefore,DNC technology has been adopted by more and more enterprises,the effective realization of the NC workshop enterprise information integration and information integration of CNC equipment,not only improve the production efficiency,but also effectively improve the management efficiency of enterprises.Based on this,considering our country enterprise actual production scale on the basis of the use of soft plug-in technology,serial server technology,NC equipment enterprise networking,and considering the actual situation of the enterprises create CNC machine tool DNC communication and management system,to achieve the enterprise information management office and workshop production information interconnection and real-time sharing.Through access to relevant information,to explore the research status of CNC machine tool DNC communication and management at present,and then combined with the actual situation of the enterprise,the CNC machine tool DNC communication and management of the design and research.Through the communication between the host and the research of DNC CNC system is the most reasonable,to achieve data upload,download and other functions;the communication technology of DNC system are analyzed and compared,based on the determined communication technology adopted by the system;at the same time,the problem of network of CNC machine tools the difficulties encountered are analyzed,and put forward the port equipment network server based on overall network control Scheme and technical route,so as to solve the problem of network difficulty.Finally,the networking scheme used in the present stage is analyzed and studied,and the suitable networking scheme is determined to complete the hardware connection of the CNC machine tool DNC system.
