A method for mechanically producing a wood structure with a decorative pattern is disclosed, wherein partial patterns are processed onto a working face of a wood structure by moving at least one milling cutter of a processing head of a device for patterning transversely to the wood structure with the axis of rotation of the milling cutter at an inclined angle relative to the place of the working face in such a way that grooves that form the partial pattern are formed on the working face, each of the grooves having two planes set at an angle relative to each other while the depth of the groove changes in the transverse direction of the groove. In the method, the wood structure is formed of at least two or more adjacently placed pieces of wood each having two edges, wherein several successive grooves are formed onto the working face of at least two pieces of wood with a single milling movement, each single milling movement beginning or ending at an edge of the piece of wood so that the partial patterns form together the pattern of the wood structure. A corresponding device for patterning and a decorative wood structure are also disclosed.

A method for manufacturing a laminate panel, where in a first step a press element is manufactured showing a surface relief. In a second step by means of the press element a relief is formed in a surface of the laminate panel, where the surface relief of the press element is provided with protrusions, which during pressing form recesses in the surface of the laminate panel. The recesses imitate wood pores. When manufacturing the press element, at least a number of the protrusions is made elongate and as such are formed substantially or essentially by a machining treatment with rotating cutting tools.

A marking stylus for use in automated marking systems with one of the following superabrasive components as the scribing tip: polycrystalline diamond or polycrystalline cubic boron nitride. The superabrasive may have one or more chamfers, as well as a sharp, rounded, or blunt tip. The superabrasive is preferably attached to the body of the stylus by one of the following methods: brazing, press fit, shrunk fit, clamped, casted, injection molded, or a high pressure high temperature cycle.

Materials for, and methods of, colorizing a metallic surface with micro-gratings using vibration cutting technologies are provided. Micro-gratings on aluminum, brass, and stainless steel surfaces can be rapidly created to effect, under illumination, at least one color observable in the visible spectrum using elliptical vibration texturing, a vibration-assisted mechanical cutting process. The modified metallic surface can display multiple visible colors, an iridescent effect caused by changes in one or more cutting parameters employed to produce the micro-gratings, the angle of illumination by an incident light, and/or the viewing angle of the surface under illumination.

To enable simple identification of a workpiece with little effort during machining of a workpiece on a processing machine, a marking method is provided which is to be carried out via the processing machine. The method includes a) providing a tool on a rotatable tool holder of the processing machine, b) relative linear movement of the tool holder and the workpiece along a line on the surface of the workpiece, and c) controlling the distance of tool holder and workpiece during the linear movement, so that a pattern of markings is produced along the line by machining with the tool to form the identification mark on the surface of the workpiece. Furthermore, a readout method, a machining method and a processing machine configured for carrying the method are provided.
