CMM inspections uses precise scanning technology that measures the geometry of any physical object. It probes discrete points on the surfaces of the object to provide precise inspection reports. This technique of measurement has been used since 1960.
A Coordinate Measuring Machine (CMM) is a high-precision dimensional metrology system designed to quantify the physical geometric characteristics of manufactured components. Utilizing a tactile or optical probing system, a CMM systematically acquires discrete scan coordinates across an object's surface to verify dimensional accuracy and geometric tolerances. CMM technology remains a fundamental pillar of industrial quality assurance, reverse engineering, and geometric dimensioning and tolerancing (GD&T) compliance.
