Abstract: A method for producing a component, wherein according to the method on at least one surface side of the component at least one parting or predetermined breaking line is produced in that first, in a thermal treatment or procedural step, the parting or predetermined braking line is locally heated by energy input, and then is abruptly cooled by means of a cooling medium such that in the component this temperature fluctuation brings about a targeted crack formation or material weakening along the parting or predetermined breaking line.

Abstract: Method for the laser ablation of brittle components in preparation for the subsequent separation of the same, by the introduction of sack-like indentations by a laser beam, wherein the indentations are arranged in a line one after the other, and form a laser ablation line which serves as the fracture initiation line, wherein the term laser ablation line means a line formed by connecting the middle points of all the indentations. At least two laser ablation lines are introduced onto the component surface and cross each other at a cross point.
