Industrial Automatic Control Systems and Controllers Annotation << Back Metrological Support of NDT Devices of New Generation E.A. Belkin, V.N. Poyarkov, O.I. Markov The substantiation of methods of application of three-dimensional geometric model of frame discretely-defi ned (hydrodynamic) surface, to determine defects of the internal and external geometry of the part surface topography and micro relief. The substantiation of methods of application of three-dimensional geometric model of the micro relief, to determine its topography. The importance of metrological support of NDT devices of new generation, on the formation of the surface layer metal structure, external and internal geometry of complex-shaped components with nana - and micrometer range the measurement accuracy and visualize it, the principle of which is based on the latest achievements in the fi eld of optical holography and diffractive optics. Keywords: oblique helicoids; a modular geometric model of gas turbine blades; the osculating parabolic; topography of micro relief.
