随着信息化建设和自动化生产制造的不断推进,数控设备已形成DNC(Direct Numerical Control,直接数据控制)网络化的状态。为了充分发挥数控编程和数控设备效率,数控设备需要与办公网络中的PDM、CAPP等应用系统进行大量信息交互,DNC数控网络系统与办公系统网之间安全防护迫在眉睫。笔者所在公司参考相关保密标准和要求,实施了DNC数控网络系统的安全防护,从实际使用效果看,安全防护得到了控制与加强。下文主要对其进行介绍,
With the continuous improvement of information construction and automated manufacturing, CNC equipment has formed a network of Direct Numerical Control (DNC). In order to give full play to the numerical control programming and numerical control equipment efficiency, numerical control equipment needs a lot of information interaction with PDM, CAPP and other application systems in the office network, and the security protection between DNC NC network system and office system network is imminent. The author’s company reference security standards and requirements related to the implementation of the DNC NC network security system, from the actual use of results, security has been controlled and strengthened. The following mainly introduces it,
