Building cyber-physical system (CPS) models of machine tools is a key technology for intelligent manufacturing.The massive electronic data from a computer numerical control (CNC) system during the work processes of a CNC machine tool is the main source of the big data on which a CPS model is established.In this work-process model,a method based on instruction domain is applied to analyze the electronic big data,and a quantitative description of the numerical control (NC) processes is built according to the G code of the processes.Utilizing the instruction domain,a work-process CPS model is established on the basis of the accurate,real-time mapping of the manufacturing tasks,resources,and status of the CNC machine tool.Using such models,case studies are conducted on intelligent-machining applications,such as the optimization of NC processing parameters and the health assurance of CNC machine tools.
