Abstract
The invention relates to a method for producing a blank, in particular a blank for the production of a cutting tool, wherein a green body extending in the direction of the extrusion axis is produced from extrusion material by means of an extruder which has an extrusion channel extending along an extrusion axis; wherein the extrusion channel together with a movable mold element forms a die of the extruder; and wherein the mold element is moved relative to the extrusion channel and within said extrusion channel during the extrusion of the green body, whereby the shaping geometry of the die is changed so that the completely extruded green body hereby has a first functional segment and a second functional segment adjacent thereto in the direction of the extrusion axis (); wherein the two functional segments differ with regard to their geometries impressed by the die.
