FIELD: mechanical engineering. SUBSTANCE: power of laser radiation passing through diaphragm is regulated proportional to speed of movement of blank under treatment. Distance between surface of the blank and focus of laser radiation is corrected. The beam is shifted relatively diaphragm hole in the direction from center of curvature of its trajectory. EFFECT: improved efficiency. 1 dwg
