摘要：
机床具有绕相对于机床坐标的所有直线运动轴倾斜的第1轴线的第1旋转进给轴。机床预先设定有工作台坐标。工作台坐标具有彼此正交的假想第1直线运动轴、假想第2直线运动轴以及假想第3直线运动轴、和绕假想第1轴线的假想第1旋转进给轴。假想第3直线运动轴与沿着主轴的轴线的方向延伸的第3直线运动轴平行。假想第1直线运动轴和假想第2直线运动轴中的一方的假想直线运动轴设定于工件安装面的表面上，假想第1轴线设定成与一方的假想直线运动轴平行。运算部运算工作台坐标的假想第1旋转进给轴的坐标值，显示部显示假想第1旋转进给轴的坐标值。
摘要（英）：

This machine tool has a first rotating feed shaft around a first axis line that is inclined with respect to all the linear motion axes of the machine coordinates. Table coordinates are set ahead of time in the machine tool. The table coordinates have an imaginary first linear motion axis, an imaginary second linear motion axis, and an imaginary third linear motion axis 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 extending in the direction of the axial line of a main spindle. 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.
