First, the case of geometric shape measurement will be described with reference to FIGS. FIG. 2 is a diagram illustrating the measurement of the end face of the work. In this case, since the probe 42 is moved in the direction of the measurement end surface 40A of the work 40 (the direction of the arrow), the moving direction of the probe 42 is most parallel to the X axis. Therefore, the plane determination unit 32 sets a plane parallel to the X axis as a measurement plane based on the moving direction of the probe 42. Then, the data processing unit 34 outputs a correction value obtained by projecting the movement amount of the probe 42 onto a measurement plane parallel to the X axis.

（Ｚ値）を出力する。FIG. 4 is a diagram for explaining the circle measurement. Since each measurement point measured by the probe 42 has the least movement in the Z-axis direction, the plane determination unit 32 determines the measurement plane as the XY plane. Accordingly, the data processing unit 34 obtains a corrected circle by projecting the measurement data on the XY plane. In the case of the ellipse measurement, the measurement is performed in the same manner as the circle measurement. FIG. 5 is a diagram illustrating the planar measurement. In FIG. 5, when the plane obtained by the probe 42 is almost parallel to the XY plane, the plane determination unit 32 determines the XY plane 44 as the measurement plane. And
The data processing unit 34 outputs the coordinate value (Z value) at the intersection of the determined coordinate plane (that is, the Z axis) perpendicular to the measurement plane 44 and the measurement plane.

The XY plane in FIG. 6 is determined as the measurement plane. Therefore, the data processing unit 34 outputs the coordinate values (X value, Y value) of the intersection between the measurement plane and the cylindrical axis. When the shape of the work is a cone measurement or a linear measurement (three-dimensional), the measurement is performed in the same manner as in the case of the cylindrical measurement.

The plane determining unit 32 determines which plane of the machine coordinate system is closest to the plane 48 designated as the XY plane of the work coordinate system as the plane reference. FIG.
In this case, the specified plane 48 is closest to the XY plane, so the plane 48 is set as the XY plane of the work coordinate system.

It is determined which Z axis of the work coordinate system of 0 (other cone, three-dimensional straight line) is closest to which coordinate axis of the machine coordinate system is most parallel. In this case, the designated cylinder 50 is Z in the machine coordinate system.
Since it is almost parallel to the axis, it is set as the Z axis of the machine coordinate system.
