Publication number: 20230219174Abstract: In a method for laser fusion cutting in particular a plate-shaped workpiece, preferably with a thickness D of at least 1 mm, a laser beam and a cutting gas, in particular nitrogen, at a cutting gas pressure are directed at the workpiece surface by a convergent cutting nozzle. The laser power is at least 6 kW and the cutting nozzle has a nozzle end face on the workpiece side. A distance A between the nozzle end face and the workpiece surface during the cutting operation is 2 to 8 mm. The cutting nozzle has a nozzle channel with a diameter dD at the nozzle end face on the workpiece side of 1.5 to 4 mm. The cutting gas pressure before emergence from the cutting nozzle is 15 to 30 bar. This makes it possible to achieve high productivity along with a reduced risk of collision, i.e. higher process reliability.Type: ApplicationFiled: March 22, 2023Publication date: July 13, 2023Inventors: Michael Krutzke, Patrick Mach, Christoph Kraus

Publication number: 20230054278Abstract: A method for determining a minimum width of a microjoint by which, when machining a workpiece, in particular a sheet-like workpiece, a workpiece part remains connected to a remaining workpiece of the workpiece. In the method, the minimum width of the microjoint is determined in dependence on at least one machining parameter which influences a relative position of the workpiece part in relation to the remaining workpiece during the machining of the workpiece. A further method determines an attachment position of such a microjoint and a still further method machines the workpiece.Type: ApplicationFiled: November 7, 2022Publication date: February 23, 2023Inventors: Florian Sepp, Simon Ockenfuss, Patrick Mach, Kai Etzel, Christoph Weiss

Patent number: 10155287Abstract: Methods and systems are implemented for forming a through hole in a workpiece using a laser beam and a process gas, such as oxygen or nitrogen, coming from a gas nozzle. A hole is formed in the workpiece using the laser beam and a process gas emerging from a gas nozzle, such that the formed hole extends only partially through the workpiece. A bulge deposited while forming the hole partially through the workpiece is removed from the workpiece surface by directing a flow of gas through the nozzle toward the workpiece surface as the nozzle is moved with the laser beam switched off, the flow of gas being delivered to the nozzle at a higher pressure than the process gas is delivered to the nozzle during forming the hole partially through the workpiece. Then, the hole is fully pierced through the workpiece by the laser beam using the process gas.Type: GrantFiled: December 11, 2015Date of Patent: December 18, 2018Assignee: TRUMPF Werkzeugmaschinen GmbH + Co.
