• the recess or recess can in principle be groove-shaped, hole-shaped or oblong-shaped, interrupted and / or continuously generated as a function of the line to be used later. Since the first recess is generated with an oversize with respect to the line to be inserted, it can be produced comparatively imprecisely by simple means, resulting in corresponding time and cost advantages. Subsequently, the first recess is filled with the curable filler.
• the first recess can basically be filled completely or only partially. Likewise it can be provided that several different filling materials are filled successively or simultaneously in the first recess.
• a second, dimensionally accurate recess is produced in the hardened filling material into which finally the cutting, scoring and / or scoring line is inserted.

• a particularly fast, simple and free of defects or air bubbles free filling of the first recess is ensured.
• Further advantages are obtained by dissolving the curable filling material in a solvent prior to filling the first recess and / or dispersing it in a dispersant. In this way, solid or particulate filler materials can be filled easily and evenly distributed in the first recess.
• At least one laser-capable and / or millable polymer and / or prepolymer is used as the curable filler material.

• Prepolymers are understood as meaning monomeric, oligomeric and / or polymeric compounds or compound mixtures which serve as precursors or intermediates and form relatively high molecular weight polymers during curing in the first recess.
• Duromers have the particular advantage that they can not be deformed by heating due to their strong cross-linking in the cured state, so that a particularly precise and variable processing by thermal or mechanical separation processes, for example by milling, filing, rasping, sawing, Laser cutting or the like is possible.
• at least one inorganic filler in particular a zinc phosphate cement, and / or a ceramic filler, in particular a silicate ceramic and / or an oxide ceramic and / or a non-oxide ceramic is used as the curable filler material.

• FIG. 1 shows a schematic plan view of a carrier plate 10 of a cutting, punching and / or scoring tool (not shown).
• the support plate 10 is in the illustrated embodiment of a hardened multiplex wood. However, in principle, other support plate materials such as steel, aluminum or aluminum alloys, plastics, carbon fiber composites and the like may be used.
• a first recess 12 is introduced by means of a milling process, which has a width of about 5 mm in the present case.
• the first recess 12 has an excess of approximately 1 mm in relation to a line 14 (see Fig. 4) to be fastened to the carrier plate 10 from the group of the cutting and / or scoring and / or scoring lines.
• the milling process can therefore be carried out relatively "coarsely” and quickly, since initially no special production precision is required, and even excess dimensions of 2 mm or more are irrelevant to the further process be provided that the first recess 12 is groove-shaped and / or formed as a continuous opening or slot or slot-like.
