    • A gauge for a coordinate measuring machine has a plurality of balls whose centers are located on at least one line inclined with respect to a reference axis in a virtual reference plane. The gauge is set on a measuring table of the coordinate measuring machine. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane. The coordinates of the center of each ball are measured by the coordinate measuring machine. Thereafter, the gauge is turned and inverted by 180 degrees about the reference axis and is set again on the measuring table. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane. The coordinates of the center of each ball are measured in the same way as above. Thus, measurement errors of the straightness of the machine axes of the coordinate measuring machine and the orthogonality between the machine axes can be easily and precisely evaluated.
    • 用于坐标测量机的量规具有多个球,其中心位于相对于虚拟参考平面中的参考轴线倾斜的至少一条线上。 量规设在坐标测量机的测量台上。 坐标轴中的一个坐标轴与参考轴相同的正交坐标被设置在虚拟参考平面中。 每个球的中心坐标由坐标测量机测量。 此后,量规绕参考轴线转动并反转180度,并再次设置在测量台上。 坐标轴中的一个坐标轴与参考轴相同的正交坐标被设置在虚拟参考平面中。 以与上述相同的方式测量每个球的中心坐标。 因此,可以容易且精确地评估坐标测量机的机器轴线的平直度和机器轴之间的正交性的测量误差。
