The description relates to a process for producing dies, especially of deep- drawn steel. Here, a surface component is obtained from a line drawing, where the edge of the surface component defines a nomimal outline (9). From the nominal outline and a nominal depth allocated to the surface component, a tool path (12, 17, 18, 19, 20) is then calculated by means of which an engraving tool is guided in such a way that the partial surface is removed.
L'invention concerne un procédé de production de plaques à gaufrer, notamment de plaques pour impression en creux en acier. A cet effet, un élément de surface est obtenu à partir d'un dessin linéaire, le bord de l'élément de surface définissant un contour théorique (9). A partir dudit contour théorique et d'une profondeur théorique associée à l'élément de surface, une trajectoire d'outil (12, 17, 18, 19, 20) est ensuite calculée, sur la base de laquelle un outil de gravure est guidé de manière que la surface partielle puisse être enlevée.
