The rapid development of Additive Manufacturing (AM) technologies has further highlighted the importance of coordinate metrology in the entire production process. AM often equivalent with reverse engineering (RE) and rapid prototyping (RP) in which the role of coordinate metrology is crucial. All AM technologies require (more or less) machine finishing operations, so coordinate metrology play key-role to production quality management. The paper will present two cases from practice: The first example is RE of the individual machine part that requires a higher scope of machining after production on 3D_Print machines. The results of coordinate metrology are a key starting point of machining of complex spatial shape. Another example is the fast processing of the results of the optical (contactless) coordinate metrology of points cloud of mass production of turbine blades. The mathematical model was tested on the optical measurement results of the turbine blades produced by PBF-LB/M (Powder Bed Fusion-Laser Beam/Metal). The developed mathematical method is easily applicable to the serial production of aircraft turbine blades made with precise casting or forging.
