Are you looking to learn Coordinate Measuring Machine (CMM) basics, including capabilities, best practices, advantages, and next-generation functions? Our free metrology resource site offers fundamental knowledge related to dimensional measurement instruments, environment requirements, selecting the right tool for the job, and various inspection processes.


1 Overview

What is a coordinate measuring machine (CMM)? A coordinate measuring machine (CMM) is a device that measures the three-dimensional geometry of physical objects by sensing discrete points on the surface of the object with a probe. CMMs typically specify a probe's position in terms of its displacement from a reference position in a three-dimensional Cartesian coordinate system (XYZ axes).

2 Capabilities and Advantages

Coordinate measuing machines (CMM) allow for three-dimensional inspection of parts. Measurements include lengths, angles, diameters, planes, cylinders, spheres and GD&T. Coordinate measuing machines have the advantage of being a very accurate, computerized for data collection, and performs complex dimensional inspections. They can also come in varoius types an styles inlcuding optical CMMs that use cameras, lasers, or white light.

3 Core Technology

Learn about the core techology that drives these tools, and the next-generation coordinate measuring machines using the principals of these tools of in new ways to bring added-value to production and quality inspection.
