Abstract

A tool for laser beam processing is provided. The tool includes an upper tool and a lower tool, which are able to be advanced toward one another by way of a press, such that at least one component is able to be fixed in a predefined position between the upper tool and the lower tool. At least one laser beam exit surface, which is part of an inner surface of the upper tool or lower tool, and at least one laser beam guide, into which laser radiation is able to be coupled and is able to be directed through the laser beam exit surface onto a processing location on the component are provided. A control device, which enables and/or disables the coupling of laser radiation into the at least one laser beam guide depending on the advancing movement between upper tool and lower tool is provided. Furthermore, a laser beam processing apparatus and a method for laser beam processing are also provided.
