Abstract

High-precision and environmentally friendly measurement of sheet product parameters is an important problem. Well-known environmentally friendly high-precision optical triangulation meters for measuring the parameters of sheet products enable one to measure the parameters only for longitudinal defects in sheet products. It is shown here that the modernization of a high-precision optical triangulation meter designed for measuring longitudinal defects in sheet metal allows trans-verse defects to be precisely measured in sheet products as well. Such a meter allows one to control the main rolling parameters in addition to measuring the longitudinal defects in sheet products. This provides environmentally friendly production of high-grade sheet products.
