Rigging technicians unload a coordinate measuring machine (CMM) from a tractor trailer at Fleet Readiness Center East (FRCE). A CMM is a device that measures the geometry of physical objects by sensing points on the surface of the object with a probe. This machine is one of two new CMMs FRCE acquired capable of large-volume measurement. Depot officials say these additional machines will improve efficiency and reduce wait times caused by maintenance and equipment calibration.
