Abstract
To reduce the electric power consumption in NC machine tools is strongly demanded in these years, because the NC machine tools are one of the main facilities in the manufacturing field. Although measurement tests of the power consumption of the whole machine tool had carried out up to now, this study focused onto the power consumption of feed drive systems. In order to investigate the factors that influence the power consumption and consider how to reduce it, mathematical model for the electric power consumption of feed drive systems in 5-axis machining center is proposed. In this report, the power consumption of each axis during linear reciprocal motion is simulated and compared with the measurement results. In addition, the power consumption during circular motion is also simulated and discussed.
