Inspection of turbines, rotor blades and housing structures
Optical 3D scanners are suited for quality control of complex freeform surfaces. Therefore, they are used for airfoil inspection of jet engines, terrestrial gas and steam turbines and turbochargers. Many turbine blades are manufactured in casting, forging, milling and grinding processes. In quality control, GOM systems support the product launch and the inspection and final acceptance in various production technologies. Color deviation maps as well as 2D and 3D analyses of shape, position and thickness help to draw conclusions about manufacturing effects. 3D metrology also accelerates maintenance, service and upgrading of turbines by identifying defective areas or parts to be replaced, checking that sufficient material has been applied and inspecting the post-processing procedure.
