ABSTRACT:
A process of cutting thick metal workpieces wherein a cutting laser beam is inclined back from a cutting direction and oscillated in a direction parallel with the cutting direction while a gas jet is directed from above the workpiece at an angle approximately normal to the direction of the laser beam incident on the workpiece to blow away the laser melted material as it is produced.
