Abstract
To advance technology of 5-axis control machining centers and future machine tools, it is essential to improve not only the performance of linear axes but also that of rotary axes. Therefore, direct drive motors (DDMs) employed for rotary axes of machine tools was developed by using the quality engineering and the FEM analysis of the electro-magnetic field. In this paper, the improvement impact on the performance of rotary axes from DDMs is described, and the influence of a workpiece position on the machine tool table on the kinematic performance is evaluated. Moreover, a novel method for tuning servo parameters automatically is proposed in order to improve the kinematic performance of a table axis with a workpiece which employs the DDM.
