Hexagon Metrology https://hexagonmetrology.us produces some of the most well known Coordinate Measuring Machine (CMM) solutions. A CMM is a device for measuring the physical geometrical characteristics of an object. This machine may be manually controlled by an operator or it may be computer controlled. Measurements are defined by a probe attached to the third moving axis of this machine. Probes may be mechanical, optical, laser, or white light, amongst others. A machine which takes readings in six degrees of freedom and displays these readings in mathematical form is known as a CMM.

Below, I have included the links to the free Hexagon Metrology 001 - Fundamentals e-Learning Courses. These courses have a wealth of information providing the ins and outs of CMM.
