Coordinate Measuring Machines

This category includes machines used to measure an object’s geometry through discrete surface point sensing via probe, commonly either a laser, optical probe, mechanical probe, or white light. Coordinate Measuring Machines (CMMs) can be calibrated to complete repeated measuring tasks automatically without reprogramming after each use. CMMs commonly use micrometer precision to track probe movement along three axes, producing a ‘point cloud’ mapping the object’s surface. CMMs are commonly used to test a machined part against its intended pattern for accuracy of manufacture.
