Glossary: Coordinate Measuring Machine (CMM)

 
 
A coordinate measurement machine (CMM) typically uses probes to sense the position of a point in space, measuring it based on its distance from a three-dimensional reference position. CMMs are often used to ensure a part or assembly falls within a specified range (tolerance) of the design intent. The probe gathers the points through a human operator or via automation through a process called direct computer control (DCC). The DCC CMMs can assess identical objects over and over through programming.
