摘要

A coordinate measurement machine (CMM) includes a manually-positionable articulated arm having first and second ends. The articulated arm includes a plurality of arm segments and a plurality of rotary joints. The first end includes a connector configured to connect to a measurement probe. The second end includes a base for mounting the CMM. A housing of at least one rotary joint from the plurality of rotary joints has a cylindrical outer surface that engages a) the base or b) a connecting portion that connects the at least one rotary joint to another rotary joint from the plurality of rotary joints, the housing welded to the base or to the connecting portion.
