DNC System Construction And Security Protection Research CNC Machine Tools In Enterprise

CNC machining technology manufacturing companies generally develop along two main lines, one is cutting technology, the other one is the application of computer-related technologies, the use of computer aided design, manufacturing and other functions of the systematic application software, these applications achieve integration between systems, promote FMS / CIMS and other new technology deployment and applications, ultimately, to digital manufacturing workshops, research and exploration of digital manufacturing plant. DNC(Distributed Numerical Control) called distributed numerical control technology, is a comprehensive utilization of a variety of advanced digital technologies to connect with decentralized production site CNC machine tools and other equipment, set up a business DNC network.In this paper, from the engineering point of view, the scene of military enterprises CNC machine tools factory usage analysis, combined with the demand for network manufacturing military enterprises, put forward ideas and methods DNC factory building enterprise networks and applications. By studying the DNC related technologies, combined with the principle of selection DNC system and the company’s future production and development needs, we proposed to build the required DNC network hardware, software and cabling implementation methods, and planning for the plant out of the reality of digital control machine global design methods and processing equipment DNC networking systems.Particularity secret military enterprises DNC network access campus network, the paper focuses on the security of the enterprise CNC machine tools DNC system were studied. DNC system under the guidance of the overall design scheme o f things, for the DNC network incorporated security issues introduced secret enterprise campus network, proposed the corresponding solutions, successfully constructed DNC network security systems. Not only to achieve multiple CNC equipment for plant information management directly through the network, played a CNC machine processing efficiency, while ensuring that the information can be effective and safe to use.
