摘要： This machine tool has a first rotating feed shaft around a first inclined axis line. Table coordinates are set ahead of time in the machine tool. The table coordinates have imaginary first, second and third linear motion axes that are perpendicular to each other, and an imaginary first rotating feed axis around an imaginary first axis line. The imaginary third linear motion axis is parallel to a third linear motion shaft. One imaginary linear motion axis of the imaginary first linear motion axis or the imaginary second linear motion axis is set above the surface of a workpiece attachment surface, and the imaginary first axis line is set parallel to the one imaginary linear motion axis. A computation unit computes the coordinate values of the imaginary first rotating feed axis in the table coordinates, and a display unit displays the coordinate values of the imaginary first rotating feed axis.

摘要： A method for controlling the motor of a tool magazine that rotates around a horizontal rotation axis is configured so that: at least two indexing positions for the tool magazine are determined; the load torque acting on the tool magazine when stopped at said indexing positions is measured; an unbalance torque, which is the load torque when stopped at the indexing position at which the load torque when stopped is maximal, is calculated from multiple load torques when stopped; and the servo motor for the tool magazine is controlled on the basis of the unbalance torque.
