Abstract
Methods, devices, apparatus, and systems are described for separating workpiece parts from workpieces using a focused machining beam. The methods include creating a trough in the workpiece using the focused machining beam, the trough being created along at least one section of a contour of the at least one workpiece part to be separated from the workpiece, altering a focal position of the machining beam such that the machining beam has a smaller beam diameter on the workpiece, and creating a gap in the workpiece using the machining beam with the altered focal position along at least one section of the contour of the at least one workpiece part to be separated from the workpiece. The gap is created at least partially within the trough.
Claims16
A method of beam machining of a workpiece, from which at least one workpiece part is to be separated, using a focused machining beam, the method comprising:
- creating a trough in the workpiece using the focused machining beam by moving the focused machining beam along at least one section of a contour of the at least one workpiece part to be separated from the workpiece, wherein the trough is elongated and extends along a length of the at least one section of the contour;
- altering a focal position of the machining beam such that the machining beam has a smaller beam diameter on the workpiece;
- and
- creating a gap in the workpiece by moving the machining beam with the altered focal position along a path corresponding to the at least one section of the contour of the at least one workpiece part to be separated from the workpiece, wherein the gap is created at least partially within the trough,
- wherein creating the gap in the workpiece comprises at least one of:
- i) creating a closed gap along the path corresponding to the contour of the at least one workpiece part to cut the at least one workpiece part free, or
- ii) creating a gap interrupted by at least one web along the contour of the at least one workpiece part,
- wherein, by separating the at least one workpiece part from the workpiece, the at least one workpiece part is cut free out of the workpiece such that a hole is created in a remaining part of the workpiece.
A beam machining device comprising:
- a beam head configured to guide a machining beam;
- and
- an electronic control device configured to control beam machining of a workpiece, from which at least one workpiece part is to be separated, using a focused machining beam, wherein the electronic control device is configured to control operations comprising:
- creating a trough in the workpiece using the machining beam by moving the focused machining beam along at least one section of a contour of the at least one workpiece part to be separated from the workpiece, wherein the trough is elongated and extends along a length of the at least one section of the contour;
- altering a focal position of the machining beam such that the machining beam has a smaller beam diameter on the workpiece;
- and
- creating a gap in the workpiece by moving the machining beam with the altered focal position along a path corresponding to the at least one section of the contour of the at least one workpiece part to be separated from the workpiece, wherein the gap is created at least partially within the trough,
- wherein creating the gap in the workpiece comprises at least one of:
- i) creating a closed gap along the path corresponding to the contour of the at least one workpiece part to cut the at least one workpiece part free, or
- ii) creating a gap interrupted by at least one web along the contour of the at least one workpiece part,
- wherein, by separating the at least one workpiece part from the workpiece, the at least one workpiece part is cut free out of the workpiece such that a hole is created in a remaining part of the workpiece.
A non-transitory computer-readable storage medium coupled to at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to control operations of beam machining of a workpiece, from which at least one workpiece part is to be separated, using a focused machining beam, the operations comprising:
- creating a trough in the workpiece using the machining beam by moving the focused machining beam along at least one section of a contour of the at least one workpiece part to be separated from the workpiece, wherein the trough is elongated and extends along a length of the at least one section of the contour;
- altering a focal position of the machining beam such that the machining beam has a smaller beam diameter on the workpiece;
- and
- creating a gap in the workpiece by moving the machining beam with the altered focal position along a path corresponding to the at least one section of the contour of the at least one workpiece part to be separated from the workpiece, wherein the gap is created at least partially within the trough,
- wherein creating the gap in the workpiece comprises at least one of:
- i) creating a closed gap along the path corresponding the contour of the at least one workpiece part to cut the at least one workpiece part free, or
- ii) creating a gap interrupted by at least one web along the contour of the at least one workpiece part,
- wherein, by separating the at least one workpiece part from the workpiece, the at least one workpiece part is cut free out of the workpiece such that a hole is created in a remaining part of the workpiece.
