What is a coordinate measuring machine?

August 19, 2025

A coordinate measuring machine (CMM) is an instrument used to collect measurements of three-dimensional objects. It acts like a high-precision three-dimensional ruler, used to measure the dimensions and tolerances of complex parts.

When you want to measure an object, such as an automotive part, you secure it to a platform. Then, the machine's "hand" (actually a very precise probe) moves around the object, gently touching different parts and recording the spatial location of each contact point. This allows it to determine the object's length, width, and height, and even determine whether its shape meets design requirements.
