Articulating Arms Smaller and Lighter Than Traditional CMMs
Articulating arms are portable and make inspection easier, since operators can move them to measure a part as opposed to moving the part to the CMM.
3D measurement arms, also referred to as articulating arms, are portable coordinate measuring machines (CMMs) that pinpoint and record the location of a probe and record the results through software.
These arms use encoders, or special glass parts, to measure a probe’s location. They range from 2 to 6 feet, but some can reach double that. However, shorter arms tend to be more accurate and precise. These arms can encompass a wide range of motion, and typically come with 6 axes of rotation.
