WebA coordinate measuring machine (CMM) works in much the same way as your finger when it traces map coordinates; its three axes form the machine's coordinate system. Instead of a finger, the CMM uses a probe to measure points on a workpiece. Each point on the workpiece is unique to the machine's coordinate system. A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensor do exist. Depending on the machine, the probe position may be manually controlled by …
