A coordinate measuring machine which operates in accordance with a cylindrical coordinate system which includes a linear Z-axis, a linear r-axis which extends perpendicular to the Z-axis, and a rotational angle PHI around the Z-axis. According to the invention the coordinate measuring machine includes a first stationary part (1), a foot, which supports the movable machine parts, a second part (2) which has the form of a column projecting from the foot (1) and which includes means which are rotatable around the Z-axis relative to the stationary part and to a selected rotational angle PHI . The machine also includes a third part (3) in the form of a first arm which extends perpendicular to the Z-axis and carries a measuring probe (5), either directly or indirectly, wherein the arm (3) coacts with means for moving the probe in the direction of the r-axis. The machine includes a further part (4) which can be moved in the direction of the Z-axis for moving said probe (5) in the direction of said Z-axis and the probe includes a measuring arm (6) whose tip carries a measuring ball (7) or like device, wherein the measuring arm is attached to the machine so that the probe will be moved when one of the second (2), the third (3) or the further part (4) is rotated or moved axially and wherein the measuring arm (6) of the probe (5) is mounted for rotation about an axis parallel with the Z-axis. <IMAGE> |
