Patent ID: 8127458

Claim:
An articulated arm CMM comprising: an articulated arm comprising a plurality of articulated arm members, a probe, a receiving portion at a distal end comprising a threaded portion, and a base at a proximal end; a base plate mounted on the receiving portion, the plate comprising a hole positioned such that the probe passes through the hole, the base plate coupled to a laser and an optical sensor located on opposite sides of the hole, wherein the base plate mounts on the receiving portion by a kinematic mount; a nut threadably mounted to the threaded portion of the receiving portion; and a wave spring mounted on the receiving portion between the nut and the base plate, such that movement of the nut along the receiving portion causes the wave spring to urge the base plate against the articulated arm to secure the kinematic mount, the wave spring mechanically isolating the base plate from the articulated arm.
