How does a CMM work?

A CMM machine (Coordinate Measuring Machine) is an essential tool used for measuring the physical geometrical characteristics of an object. It works by using a probe, which touches the surface of the object at various points to record its dimensions and shape. The CMM machine operates with either a mechanical, optical, laser, or white light probe, depending on the application. It precisely records the X, Y, and Z coordinates of the object’s surface, allowing for detailed analysis and quality control. These measurements are then compared to the desired specifications to ensure the accuracy of the part. With its ability to perform highly accurate measurements.
