Paper Abstract

3D Non-contact Inspection systems are becoming more capable and affordable, however successful application to complex parts requires understanding the remaining system limitations. Turbine airfoils are key components used in several important industries that present some unique challenges to any metrology application. Issues such as surface finish, complicated shapes and unique geometries exercise many of the key capabilities of a non-contact 3D measurement system. Therefore, many of the short comings of any 3D method become evident in addressing airfoil measurement applications. This paper will address the key challenges posed by complicated shapes such as airfoils, and what gaps still exist in the application of the technology.
