ABSTRACT:
A coordinate measuring machine for measuring parts using cylindrical coordinates. The machine includes a base, an articulated arm mounted to the base at its proximate end for movement within a plane, and a vertically movable probe assembly mounted near the distal end of the articulated arm. A horizontal measuring rod extends between the distal end of the arm and the base to provide a measurement of the location of the probe with respect to the base, in terms of a radius and an angular displacement. The probe assembly includes means for measuring perpendicular displacement of the probe from the plane of the articulated arm.
