A Coordinate Measuring Machine (CMM) is a device used to measure the geometry of physical objects by sensing discrete points on the object’s surface with a probe.
Coordinate Measuring Machines (CMMs) are essential in manufacturing for ensuring the dimensional accuracy of parts, which is critical for components that need to fit precisely together. CMMs utilize a probe to contact or scan the surface of an object, capturing precise measurements that can be used for quality assurance and to verify mechanical properties against design specifications.
A CMM measuring the dimensions of a turbine blade with a precision of ±0.002 mm (±0.00008 inches).
Used extensively in aerospace manufacturing to ensure turbine blades meet stringent safety and performance standards.
Verification of an automotive gearbox housing dimensions with tolerances up to ±0.01 mm (±0.0004 inches).
Utilized in automotive manufacturing to ensure critical components fit together seamlessly during assembly.
