The 3D measuring arms, also known as articulated arms, are mobile coordinate measuring instruments (CMMs) which allows quality control, inspection and verification of small to large size parts in the workshop.
The articulated arms record the 3D position of a probe in space and send the results to a PC software. (Examples of software for data report and analysis: Aberlink, Polyworks…)
Why do we call this portable CMM “Measuring Arm”?
This instrument is constructed like a human arm with shoulder, elbow, forearm, and a wrist. It is usually used in manufacturing environment where the object to be measured cannot be moved. In such cases it is the measuring arm that is brought to the work piece as it is portable and light. The ultimate measuring arms have carbon structure in order to make them lighter and thus making 3D measurements extremely easy. It is ideal for the measurement of large parts in the workshop.
