Study of profilograph features for determining the geometric characteristics of products by laser scanning

The work is devoted to study of profilograph features for determining geometric characteristics of products by laser scanning. The control methods applied are implemented in science-based designs of technical means of control that can provide high accuracy of parameter measurement when profiling the surface of parts. The analysis of graphs of the metal sheet surface in full and Cartesian coordinates made it possible to determine the highest and lowest points of the surface, therefore to determine the profile of sheet undulation. For example, the height of metal sheet irregularities resulted from some deformations was 6,378 mm.
