Abstract
In some aspects, methods includes forming intersecting apertures in a workpiece with a laser beam by moving the laser beam along intersecting line paths, and cutting out a portion of a shape from the workpiece by moving the laser beam along a continuous final path extending around an intersection point of the intersecting line paths.
Claims23
A method comprising
- forming intersecting apertures in a workpiece with a laser beam by moving the laser beam along intersecting line paths;
- and
- cutting out a portion of a shape from the workpiece by moving the laser beam along a continuous final path extending around an intersection point of the intersecting line paths.
A computer program code configured to carry out the following method:
- moving a laser beam head along intersecting line paths to form apertures in a workpiece;
- and
- moving the laser beam head along a continuous final path extending around an intersection point of the intersecting lines to cut out a portion of a shape to be cut from the workpiece.
A sheet metal workpiece processing machine comprising:
- a laser beam head disposed on a laser beam head movement unit;
- a workpiece support comprising a plurality of supporting elements, the supporting elements being spaced apart from one another so as to support a plate-like workpiece;
- and
- a control unit in communication with the laser beam head movement unit, the control unit being configured to move the laser beam cutting head relative to the workpiece support to perform a cutting operation on the workpiece,
- wherein the cutting operation comprises:
- forming apertures in a workpiece with a laser beam by moving the laser beam along intersecting line paths;
- and
- cutting out a portion of a shape from the workpiece by moving the laser beam head along a continuous final path extending around an intersection point of the intersecting line paths.
