Abstract: Due to the lack of effective and practical on-line detecting method of multi-source energy state for machine tool,the on-line detecting index system was established by analyzing the constitution of multi-source energy state for machine tools.The on-line detecting method for multi-source energy consumption of machine tool was analyzed which included the blocking sort method and the key parameters acquisition method,and the corresponding detection system was developed.This system could not only detect the input energy,effective energy,transient efficiency and energy efficiency of workpiece machining process,but also monitor the specific energy efficiency and effective utilization rate of equipment.The effectiveness of the proposed method and detecting system was verified on CNC PL700.It could be widely used in analysis of the status information,management control and energy saving optimization research of energy consumption and energy efficiency of machining process.

Key words: machine tools, multi-source energy consumption, detecting method, detecting system
