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.
Using Intelligent Machine Control To Optimize Quality Assurance

One of manufacturing’s biggest challenges is filling the knowledge gap left by skilled employees who retire. Intelligent machine control (IMC) increases throughput regardless of who’s operating measurement and production equipment by removing the potential for human error.

To remain competitive, more shops are searching for ways to better utilize their quality workforce and supplement them with automation. But Ken Myers of Mitutoyo America explains that what automating metrology means to one person might not mean the same to another.
The long-established technology of coordinate measuring machines is now being challenged in myriad applications by the fast-emerging, highly advanced science of blue light scanning.
Take a closer look at how Hendrick Motorsports uses technology to deliver speed and actionable data to win big and gain recognition for excellence.
Here are some of the latest advances in automated measurement that can help improve the productivity and capability of your inspection processes.
The latest version of Renishaw’s 3D fixture-modelling software creates a metrology setup around a CAD model of an inspected part. With FixtureBuilder 8.0, users don’t need a coordinate measuring machine or other inspection device to confirm accuracy.
Mitutoyo America Corp.’s QM-Height Series measures height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, and free-form surface max/min heights to ±(2.4+2.1L/600) μm. Simple-to-use control panel enables most measurements to be made with one keystroke.
The coordinate measuring machine (CMM) manufacturer is entering the portable measuring arm market with the Freedom line of 24 3D articulating arms. A 6-axis model for touch probing and a 7-axis version for multisensor metrology including laser scanning are available in two accuracy levels.
