Reducing 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. Thus measuring tests of the power consumption in an NC machine tool for all components were measured in other studies up to now. This study focused onto the power consumption of feed drive systems. In this study, electric power consumption of an actual 5-axis vertical type machining center consists of X, Y, Z, B and C axes is measured. In order to investigate the electric power consumption of feed drive systems, currency and voltage of servo amplifiers are measured. At first, the measuring tests of each axis are carried out under various feed rate. As the results of the measurements, it is clarified that the power consumption depends on the motion velocity and torque. In addition, acceleration-deceleration parameters and servo gains are also changed to investigate the influences of the parameters. These parameters have big influences on the power consumption during the acceleration-deceleration process. The results of this study show that the electric power consumption might be reduced by changing the motion and parameters of the axes.
