Abstract: An arm type coordinate measuring machine includes a rotating table on which a workpiece is mounted, a probe for measuring three-dimensional coordinates of the workpiece mounted on the rotating table, a support arm that is rotatable while supporting the probe, an arm driving portion configured to rotate the support arm around a first axis, a table driving portion configured to rotate the rotating table around a second axis perpendicular to the first axis, and a control portion configured to drive the arm driving portion and the table driving portion to move the probe with respect to the workpiece such that the three-dimensional coordinates of the workpiece are measured by the probe.
