Optical 3D measurement of surface coatings on cutting tools

In this measurement report, we describe the use of optical 3D metrology to measure the coating thickness on components. By creating a "master” tool and creating a 3D dataset testing can easily be achieved by creating a 3D model of a coated product and comparing the data to measure differences without damage to the coating. The example here is a complex cutting tool which is a worstcase scenario in terms of complexity for this application.

The metrology system used for this task is the InfiniteFocus system fitted with an Advanced real3D rotation device. Users verify dimensional accuracy and surface finish of their components with only one sensor.
