In order to solve the difficulties of energy efficiency on-line monitoring of CNC machine tools, proposed an on-line ener- gy efficiency monitoring method based on the power balance equation and energy loss characteristics of machine tools. In this method, cutting power can be calculated automatically through measuring the input power of main transmission system and the to- tal power of machine tools. And then the energy efficiency of machine tools can be obtained. At the same time, the equipment utilization of machine tools was calculated based on recognizing the status of machine tools on-line using power information. A set of software and hardware solutions of the on-line energy efficiency monitoring system based on ARM and WinCE platform were proposed, and the system was developed as well. The accuracy and practicality of the system had been verified by experiment. On-line energy efficiency monitoring of CNC machine tools plays an important role in supporting energy efficiency evaluation, energy consumption prediction, energy management and energy saving, which has broad application prospect.
