Abstract
Abstract To cut or separate a workpiece, having a plain or curved surface, a jet-like fluid cutting medium is used. The cutting medium is ejected from a nozzle under high pressure and is directed towards the workpiece. In order to achieve an exact cut edge, even if a high cutting speed is selected, the cutting medium is directed towards the surface of the workpiece not exactly perpendicularly, but with an angle deviation of between 0.1 and 0.3 degrees. An apparatus for performing such a cutting operation comprises a tube with a nozzle at its end through which the cutting medium is ejected. The nozzle is swivelably supported and the tube may be adjusted in X- and Y-direction such that the desired cutting angle may be controlled.
