Patent ID: 7805851

Claim:
A coordinate measuring machine for determining a measuring position of a probe, comprising: an articulated arm having first and second ends and at least one joint between the first and the second ends, the first end forming a base being positionable on a supporting surface, the second end being movable relative to the first end and having attached the probe; at least one sensing unit for measurement of an actual relative setting of said at least one joint; and at least one computing unit for calculating a measuring position of the probe relative to the base; and for referencing the measuring position in an external coordinate system by using a provided base-position in the external coordinate system, wherein: the articulated arm includes a first inclinometer for measurement of a slope relative to an external vector referenced in the external coordinate system relative to the gravitational vector and for providing an electronic slope value; and the slope value is further used for referencing the measuring position in the external coordinate system.
