FIELD: laser technology, namely dimensional working of composition materials at making complex-contour articles. SUBSTANCE: method comprises steps of using complex mode of irradiation; directing beam focus inside material by depth equal to distance from surface in range 1/2 - 5/8 of its thickness; sustaining irradiation intensity in range 500 - 700 Wt; selecting motion speed of beam in range 0.8 - 2.5 cm/s. EFFECT: high quality of cutting in upper and lower surfaces of material at minimal zone of thermal influence. 1 tbl, 1 ex |
