Abstract
The invention relates to a method of producing an aperture in a metallic component, in which the aperture comprises, at least in certain portions, a non-cylindrically formed funnel, extends from a first surface to a second surface of a component wall and is formed by a laser beam. The invention improves the dimensional accuracy and reduces the roughness of the surface of the aperture and/or funnel in that, by appropriate choice of the laser parameters, the metal is predominantly removed by sublimation during the formation of the funnel and the funnel is formed by laser removal of layers of a substantially constant thickness.
