3D Metrology What is 3D metrology?

 .

Metrology is the science of measurement. It establishes a common understanding of units, crucial in linking and understanding human activities. When we apply metrology to the field of 3D this generally refers to measuring size, volume, and depth.

 .

When dealing with objects it is important to have precise measurements of their size for various reasons. You may need to do Quality Assurance to see if your product is as specified or may be looking for defects and anomalies. A very important part of 3D metrology is the ability to have measurement data that helps the production of manufacturable products.

 .

3D metrology is typically conducted with the use of hand tools, CMM technology, machine vision systems, laser trackers, scanners, and optical comparators. CMM technology refers to coordinate measuring machines. A CMM is typically done with a touch probe, scanning contact probe, or non-contact sensor. […]
