FIELD: process engineering.
SUBSTANCE: invention relates to cutting of fragile nonmetallic materials, for example, quartz glass, etc. Proposed method comprises making a local notch at workpiece edge in cutting line, heating the latter by laser beam and cooling it by coolant at relative displacement of material and laser beam with coolant. For cutting, workpiece is heated by laser beam before making said notch to be made in laser beam zone or immediately there behind. Notch is made at relative displacement of workpiece at the rate v with time delay with respect to beginning t of heating by laser beam defined by equation t=Ask/v where A is half the elliptic beam in direction of displacement or round beam radius, k varies from 1 to 2.5.
EFFECT: expanded possibilities owing to application of LUT cutting method.
