Abstract:After analyzing the main problems that need to be solved in the numerical control processing of military enterprises,this paper puts forward a set of secure DNC NC program management and transmission solution based on the multi level control transmission platform of industrial control system(ICS). Through practical application,this solution realizes the security isolation and real-time exchange of data between the industrial control network and the internal network,and realizes the unified management,the interactive transmission and the version control of the NC files and the configuration files of the NC machining,which realizes the on-line machining of the CNC equipment and the batch transmission,and improves the efficiency of the machine.
