FIELD: technological processes. ^ SUBSTANCE: invention is related to method and system of application of sign and graphic information on items and may be used for laser marking, engraving in different fields of engineering. Physicochemical transformation of multi-layer coating is implemented by means of laser radiation effect onto stock with constant monitoring of parameters and correction of program of sign and graphic information application. System consists of laser radiation source, optical system for focusing of radiation and deflection system, which have control input from computer, system of stock fixing, analysing device, which is installed in system of stock fixing, and external source of light with variable brightness. ^ EFFECT: provides repetition and homogeneity of light technical properties of items; reduction of cost of their manufacture. ^ 2 cl, 2 dwg |
