FIELD: metallurgy.
SUBSTANCE: preliminary construction of calibration curve of dependence of etching depth of specimen surface of the specified metal or its alloy on parameters of incident laser radiation to surface is performed at monotonic increase in specific power of laser radiation from value of 0.1 J/cm2·s to the value at which molten drops are formed on etched surface. Then, spatial control of laser beam scanning on surface of metal or its alloy is performed at least as per one coordinate. Simultaneously with translational movement of laser beam there performed is its rotation with radius R. Radius R and angular rotation speed of laser beam is chosen considering the cut width and radius of laser beam.
EFFECT: improvement of the method.
