Abstract: Energy efficiency improvement and energy consumption reduction in computer numerical control (CNC) machine tools is very important to realize sustainable manufacturing. However, the energy efficiency in practical machining is very low. In the paper the computer monitoring approach and system on machine tools energy efficiency is developed in detail. Firstly, the machine tools energy consumption characteristics are researched according to various components and manufacturing stages; Secondly, the machine tools control structure and cutting properties are studied; Thirdly, the machine tools energy efficiency computing approach is put forward; Finally, the energy efficiency computer monitoring system with Fluke Norma sensor and Fluke shunt sensors is built up, and the monitoring experiment on vertical machining center is carried out. The developed computer monitoring approach and system on machine tools energy efficiency is helpful to evaluate and improve machine tools energy efficiency further.


Keywords: Energy efficiency, Computer monitoring system, Computing approach, Vertical machining center, Fluke shunt sensor.
