What is a coordinate measuring machine?

A Coordinate Measuring Machine (CMM) is a device used in manufacturing and quality control to measure the physical geometrical characteristics of an object. Using a probe that touches the object's surface, a CMM can precisely determine the coordinates of points and create highly accurate 3D measurements. CMMs are commonly used to ensure that parts and assemblies conform to their design specifications, helping maintain high levels of quality and consistency in production. They can be operated manually or controlled by computer software for automated measurements.
