An ultrasonic machining device (1) for machining a workpiece. At least one component, selected from the group including a generator (11), a converter (12), a booster (13), a sonotrode (14), a HV cable (15), a machine frame (16) and a receiving device for the workpiece (17), is/are assigned an identifier (18). The identifier (18) characterizes at least one individual parameter of the component. The device (1) is assigned an input interface (19) which reads in the identifier (18) or generated data from the identifier. The device (1) is assigned a data processing arrangement (20). By way of the data processing arrangement (20), based on the read-in identifier (18) or the data generated from the identifier (18), at least one parameter of the device (1) is determined in such a way that the device (1) is operated in a target operating state, e.g., a resonant vibrating state.

A computer-implemented method for marking an object on an aligner. The aligner surface is modeled. The method includes calculating a normal for each tile in a tessellated surface and disqualifying a tile from being selected. For tiles not disqualified, a patch is identified that produces a markable area. The method includes selecting an object to be marked, calculating a location of the object in the markable area, and providing the location of the object to a marking device. Disqualifying includes comparing an angle between a normal and an orientation of the beam to an origin of the calculated normal on each tile. Disqualifying includes disqualifying the at least one tile when the angle is outside of a range of −90° to +90°. Identifying the patch includes separating the patch into at least two smaller patches, and one of the two smaller patches of tiles is the markable area.

A method for marking a workpiece (6) uses a device, wherein the workpiece (6) is formed at least partially in a thermal master or forming process, comprises a surface (10) directed towards the workpiece (6), wherein a number of individually controllable heating elements (2) is distributed behind the surface (10) for a local heating of a workpiece surface portion. Each of the heating elements (2) comprises a solid material (11) having a surface structure and a heating structure (3), wherein the surface (10) directed towards the workpiece (6) encompassing the surface structures (40) has a uniform smooth surface allowing to dark, burn or foam the surface (7) of the workpiece (6) through heat introduction.

A polymeric article includes a body and encoded visual indicia formed on the body. The encoded visual indicia may be scanned to generate instructions. A method of providing the polymeric article includes applying polymeric materials to a mold to provide an article-blank web having formed therein an article preform of a desired shape with encoded visual indicia formed in the article preform.

A method for determining and indicating the orientation of fibers in a selected portion to be removed from a composite stock panel. The method may include determining the orientation of fibers in a composite stock panel based on a pre-existing indicator carried by the stock panel, and applying a fiber orientation indicating mark to at least part of a selected stock panel portion that is to be separated from the stock panel and from the pre-existing indicator, the fiber orientation indicating mark corresponding to the orientation of the pre-existing indicator.

An injection-moulded plastic part for a cable carrier, particularly a side part of a chain link produced in an injection moulding process. The injection moulded part has a visible, identifiable marking on a first side, particularly the outside. The at least one marking comprises a data code marking having a 2D code for data encoding which is introduced into the plastic body directly in the injection moulding process so that said marking is provided on the first side to be machine-readable. The invention likewise relates to a corresponding injection moulding tool having a number of first symbol regions and second symbol regions for producing the data code marking in the injection moulding process.

A method, medium, and system to receive an indication of an assembly including a plurality of different components to produce by additive manufacturing (AM), determine based on a forward search process that starts with individual components of the plurality of components and iteratively adds other components of the plurality of components thereto in combinations until an entirety of the assembly is accounted for, determine based on a reverse search process that starts with the entirety of the assembly and iteratively removes components of the plurality of components therefrom in combinations until a two-component set is reached, automatically select an optimal combination of the plurality of components from the combinations determined by the forward search and reverse search processes; and transmit the selection of the optimal combination of the plurality of components to an AM controller.

An embossing apparatus which forms an emboss pattern on a sheet-type workpiece, comprising: a mounting unit on which an embossing pen for embossing is mounted; a transfer mechanism configured to move the workpiece and the mounting unit relative to each other; and a controller configured to control the transfer mechanism, the controller being configured to control the embossing apparatus to: identify a contour of a predetermined shape, set a region offset inward or outward by a predetermined amount from the identified contour of the predetermined shape as an offset region, generate pressing data for use to press part of the workpiece which corresponds to the set offset region, and press the workpiece with the embossing pen according to the generated pressing data.

An embossing apparatus which forms an emboss pattern on a sheet-type workpiece using a template sheet with the emboss pattern cut out therefrom, the embossing apparatus comprising: a mounting unit on which both a cutter member for cutting and an embossing pen for embossing are mounted simultaneously or one of the cutter member and the embossing pen is mounted alternatively; a holding member configured to hold the template sheet and the workpiece; a transfer mechanism configured to move the holding member and the mounting unit relative to each other; and a controller configured to control the transfer mechanism, the controller being configured to control the embossing apparatus to: specify the emboss pattern, cut the specified emboss pattern out of the template sheet held by the holding member using the cutter member mounted on the mounting unit by controlling the transfer mechanism, and press part of the workpiece which corresponds to a cutting region cut out, using the embossing pen mounted on the mounting unit by controlling the transfer mechanism, the workpiece being placed on the template sheet held by the holding member.
