Claim Text:
1. A method for producing a blank ( 1 ) from a fiber layup ( 5 ) having an edge ( 3 ) forming a chamfer ( 2 ), wherein the fiber layup ( 5 ), which is suctioned onto a cutting support ( 6 ) of a cutting table ( 7 ), is cut through using a contour cut ( 17 ), which extends into the cutting support ( 6 ), along the intended contour ( 4 ) of the blank ( 1 ) and is provided with the chamfer ( 2 ) using a chamfer cut ( 16 ) running at a flat chamfer angle (α) along the intended contour ( 4 ), wherein the fiber layup ( 5 ) is firstly precut by two cuts, which end above the cutting support ( 6 ) and run outside the intended cross section of the edge ( 3 ), namely a preliminary cut ( 10 ) running transversely to the fiber layup ( 5 ) along the contour region and a relief cut ( 11 ), which determines a processing allowance ( 15 ) to the chamfer ( 2 ), and then the chamfer ( 2 ) is cut using the chamfer cut ( 16 ), which ends outside the intended contour ( 4 ) in the fiber layup ( 5 ), before the intended contour ( 4 ) of the blank ( 1 ) is produced by the contour cut ( 17 ).
