FIELD: laser technologies.
SUBSTANCE: invention relates to a method for laser processing of a metal material by means of a focused laser beam having a given transverse power distribution, a laser processing machine and a machine-readable information carrier. The laser beam is guided along the optical path of the beam transport to the working head, the laser beam is collimated along the optical axis of propagation, and the collimated laser beam is focused on a section of the working plane of the material. A laser beam is formed by reflecting a collimated beam by means of a deformable element reflecting a controlled surface that has a certain number of independently moving reflection sections. The auxiliary gas flow is supplied in the direction of the area of the working plane of the metal material and the specified flow is controlled. The relative movement of the said auxiliary gas flow axis is controlled in accordance with intermediate directions along a preselected smoothing curve. The said smoothing curve is removed from the pre-selected working path by a distance of no more than the radius of the feed zone of the said flow. The location of the reflection sections is controlled to establish the position of the movement of the optical axis of the laser beam in the area of the working plane on the metal material located in a predetermined area around the axis of the auxiliary gas flow and in the supply zone of the said flow.
EFFECT: ensuring the stability of positioning between the optical axis of the laser beam propagation and the auxiliary gas outflow axis by adjusting the relative position of the optical axis of the laser beam propagation and the auxiliary gas flow axis.
