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.
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).
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.
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.
