koordinatmåttmaskiner

Koordinatmåttmaskiner, often abbreviated as CMMs, are precision measuring instruments used to determine the geometric characteristics of manufactured parts. They operate by moving a sensor along a three-dimensional coordinate system. This sensor, typically a probe, touches the surface of the object being measured. The CMM records the coordinates of these contact points, allowing for the creation of a digital model of the part's dimensions and form.

These machines are crucial in quality control and manufacturing processes across various industries, including automotive, aerospace, and medical device production. CMMs provide highly accurate and repeatable measurements, which are essential for ensuring that components meet strict design specifications and tolerances. They can measure a wide range of features, such as lengths, diameters, angles, and complex curves.

There are several types of CMMs, including bridge, gantry, horizontal arm, and cantilever designs, each suited for different applications and workpiece sizes. The probe itself can also vary, with touch-trigger probes, scanning probes, and non-contact optical probes being common. The data collected by a CMM is processed by specialized software, which generates reports, performs analysis, and can even be used for reverse engineering. Their ability to automate the measurement process significantly reduces the time and potential for human error compared to manual inspection methods.
