<p>The method involves utilizing a fluid jet (8) as a cutting tool, and accelerating the fluid jet on a predetermined jet velocity. The fluid jet is radiated on a surface area (11) of a workpiece (10) to be cut with predetermined kinetic energy. A cut edge (9) is generated in the workpiece, where the cut edge is vertical to the area. The fluid jet is formed from a medium, and particles of an abrasive additive (4) are dispersed in the medium, where the additive comprises anti-corrosion properties. The additive is applied as an anti-corrosion coating during cutting of the workpiece on the cut edge. The medium is selected from a group consisting of water, low-viscosity mineral oil, petroleum and/or solvent i.e. isopropanol. The abrasive additive is selected from a group consisting of a granular material e.g. zinc, aluminum, alloy material, corundum, ceramic material, quartz sand and/or volcanic rock, nickel, bronze and/or oxide. Independent claims are also included for the following: (1) a gumption unit comprising a gumption additive (2) a device for cutting a coated workpiece comprising a storage for storing medium.</p> |
