The electronic processing data indicate on the workpiece 2 to be produced by laser machining component properties, for example, where and in what form openings or openings to be made by laser processing. Similarly, this may be provided for further processing, for example threading. For this purpose, optionally user inputs can be detected via an input device, for example a keyboard, which are taken into account in the electronic processing data. If a collision with the electronic design data is detected by the central control device 30, for example, such that the user input provides laser processing in a protected area of the control cabinet which is locked for laser processing, the central control device 30 prevents this processing and outputs optionally a corresponding indication to the user, for example via a display device, such as a display. A protected area may, for example, relate to a sealing area in which a component to be protected (blocked for laser processing) can already be arranged, for example a seal.

For detecting the user input, a user menu may be displayed on the display, which allows the user to define manufacturing features (eg, breakthroughs) for the cabinet component to be manufactured, wherein the collected user preferences may then be compared to electronically stored defaults, for example, restrictions on laser processing.

It may be provided to detect the electronic design data by means of an SD scanning device when the cabinet component to be processed is arranged on the work table. Alternatively, existing design data may be loaded into a data store of the central controller.

In this way, the device is programmed for the machining of the control cabinet component or components, in order to automatically execute the machining, in particular the laser processing. lead, for example, already painted control cabinet components. In particular, control data regarding the position and shape of openings and recesses to be produced on the device are provided in this way, in order subsequently to carry out the machining of the workpiece 2 accordingly.

The features disclosed in the foregoing description, the claims and the figures may be of importance both individually and in any combination for the realization of the various embodiments.
