FIELD: process engineering.
SUBSTANCE: invention relates to thermal separation by laser-inducer power. Proposed method of separating plates from ceramic or other fragile material comprises scanning the plate along specified line of separation by laser beam for feeding heat in the plate to develop thermal strains in plate material. Note here that said strains cause rupture along said separation line. Note also that said separation line is scanned many times in one direction. Note here that individual scans are separated by appropriate pause with duration selected and adjusted subject to particular material to be separated.
EFFECT: decreased rejects in cutting.
