Development of the technology of 0NBC code formation on a metal surface by laser marking

In this work, the formation of a two-dimensional code, NBC, using laser marking is considered. A complete factorial analysis was carried out to determine the optimal laser irradiation parameters for obtaining the most contrasting image of code cells on a metal surface (steel AISI 321) using laser marking. The regression equation is obtained, the coefficients of the equation are checked for signification, and the equation is checked for adequacy, an interpretation of the equation coefficients is given, the optimal laser marking parameters are obtained.
