Removing material to change shape or size (e.g., milling, turning, drilling, laser cutting). Joining (Fügen):
: Bringing two or more solid bodies together to create a new, larger part with increased cohesion. Examples: Welding, soldering, gluing, screwing, riveting.

| Main Group (Order Number) | Description | Example Processes | | :--- | :--- | :--- | | (Urformen) | Creating a solid body from a shapeless material, establishing its basic form and cohesion. | Casting (e.g., sand casting, die casting), sintering (powder metallurgy), additive manufacturing (3D printing). | | 2. Forming (Umformen) | Changing the shape of a solid body while keeping its mass and material cohesion intact. | Rolling, forging, bending, deep drawing, extrusion, stamping, spinning. | | 3. Cutting (Trennen) | Intentionally changing the cohesion of a workpiece, usually by local separation. | Turning, milling, drilling, sawing (machining with geometrically defined cutting edges), grinding, lapping (with geometrically undefined cutting edges), blanking, flame cutting. | | 4. Joining (Fügen) | Permanently connecting two or more workpieces. | Welding, brazing, soldering, adhesive bonding, riveting, screwing. | | 5. Coating (Beschichten) | Applying a layer of solid, liquid, or gaseous material to a workpiece surface. | Painting, electroplating, physical vapor deposition (PVD), anodizing, chemical vapor deposition (CVD). | | 6. Modifying Material Property (Stoffeigenschaften ändern) | Intentionally changing the material properties of the workpiece. | Heat treatment (e.g., annealing, hardening, tempering), case hardening. | based on whether they create, increase, decrease, or

Group 6: Modifying Material Properties (Stoffeigenschaften ändern)
Locally separating material to modify a shape, which results in a reduction of the workpiece mass.
