Verfahren zum Scherschneiden hochfester Werkstoffe und Schneidwerkzeuganordnung

The invention relates to a method and a cutting tool arrangement for shearing high-strength materials, characterized in that the shearing is carried out against a fluid-based damping force of a damping fluid supply (8) and the cutting tool arrangement has a cutting tool (20) arranged in a damping fluid supply (8) in the region of a cutting contour opening (4a) of a cutting plate or cutting die (4) of the cutting tool (20), in particular in order to carry out the method. The damping fluid supply (8), preferably a lubricating oil or another damping liquid which, if necessary, contributes to the damping force in the form of a counter force to a cutting force of the cutting punch (3) by virtue of its viscosity, produces a counter force acting on the cutting punch (3) during the shearing process and thus leads to a substantial reduction of a cutting impact such that even conventional cutting tools can be used to shear high-strength steel sheet materials in a reliable manner
