Abstract
Method for cutting a planar and/or metal workpiece along a predefined cutting contour using a laser beam and a cutting gas emitted from a nozzle, wherein the laser beam makes a recess in the workpiece so as to form a recess hole (on the cutting contour or at least partly close to the cutting contour. At least two machining parameters are continuously modified during formation of the recess hole, and/or at least one machining parameter is continuously modified on a switch path between the recess hole and an endpoint lying on the cutting contour.
Claims12
A method for cutting a workpiece along a predetermined cutting contour, the method comprising:
- discharging a laser beam and a cutting gas from a nozzle;
- directing the laser beam to penetrate into the workpiece to form a penetration hole on the cutting contour or at least partially beside the cutting contour;
- and
- continuously changing at least two processing parameters during the formation of the penetration hole and/or continuously changing at least one processing parameter while forming a switching path between the penetration hole and an end point located on the cutting contour.
