METHOD FOR CUTTING A WORKPIECE USING A LASER BEAM

The invention relates to a method for cutting a preferably planar and/or metal workpiece (2, 2') along a predefinable cutting contour (100, 100') using a laser beam (6) and a cutting gas (7) emitted from a nozzle (8), wherein the laser beam (6) makes a recess in the workpiece (2, 2')...

Zusammenfassung:	The invention relates to a method for cutting a preferably planar and/or metal workpiece (2, 2') along a predefinable cutting contour (100, 100') using a laser beam (6) and a cutting gas (7) emitted from a nozzle (8), wherein the laser beam (6) makes a recess in the workpiece (2, 2') so as to form a recess hole (101, 101') on the cutting contour (100, 100') or at least partly close to the cuttingcontour (100, 100'). The invention is characterised in that at least two machining parameters are continuously modified during formation of the recess hole (101, 101'), and/or at least one machining parameter is continuously modified on a switch path (107') between the recess hole (101, 101') and an endpoint (108') lying on the cutting contour (100, 100'). 本发明涉及一种用于借助激光射束(6)和从喷嘴(8)出来的切割气体(7)沿着能预给定的切割轮廓(100、100')切割优选是板状的和/或金属的工件(2、2')的方法，其中，所述激光射束(6)刺入到所述工件(2、2')中以构造在所述切割轮廓(100、100')上或者至少部分在所述切割轮廓(100、100')旁边的刺入孔(101、101')。本发明的特征在于，在所述刺入孔(101、101')的构造期间使至少两个加工参数和/或在转换区段(107')上使至少一个加工参数连续地改变，所述转换区段位于所述刺入孔(101、101')和位于所述
