Abstract: An assessment and control method, system and device for time-energy efficiency of CNC machine tools. The method comprises: comprehensively analyzing the influence of factors of the startup rate and extra startup frequency of a CNC machine tool on the energy efficiency of the CNC machine tool, and constructing a mathematical model of the time-energy efficiency of the CNC machine tool and the startup rate and extra startup frequency of the CNC machine tool. The time-energy efficiency of the CNC machine tool is monitored to realize the overlimit warning function for the time-energy efficiency of the CNC machine tool to finally control the time-energy efficiency of the CNC machine tool within a target range. The present invention analyzes the influence of the downtime loss of the CNC machine tool on the energy efficiency of the CNC machine tool, and can realize overlimit warning for time-energy efficiency of the CNC machine tool.
