The standard is the fundamental German norm for the classification of manufacturing processes. It provides a systematic order for all industrial production methods, primarily within the metalworking industry, based on how they alter the cohesion of a material. The Six Main Groups of DIN 8580
This involves the permanent, plastic deformation of a solid body. The material's cohesion is maintained, but its shape is changed. Key examples include forging, rolling, bending, and deep drawing.
DIN 8580 is the foundational German standard for classifying manufacturing processes into based on how material cohesion is changed.
The operational logic of rests on a material's cohesion—specifically whether a process creates, increases, decreases, or maintains the absolute mass concentration of a workpiece.

: Combining multiple components or applying surfaces.
Coating involves applying an adherent layer of shapeless material to the surface of a workpiece to protect it or improve aesthetics. Basic principles of metal forming | Springer Nature Link
Separating alters the shape of a workpiece by locally destroying its material cohesion, typically resulting in the generation of chips or scrap. The standard is the fundamental German norm for
is a fundamental German industry standard (published by the Deutsches Institut für Normung) that provides a systematic classification of manufacturing processes . It serves as a root framework for other more specific standards (like DIN 8583 for forming or DIN 8584 for machining).
Changing the shape of a solid body by applying force, without adding or removing material (e.g., forging, rolling, bending).
Joining involves bringing two or more separate workpieces together to create a new, larger entity. This results in a local increase in material cohesion. The material's cohesion is maintained, but its shape
Welding, soldering, brazing, adhesive bonding, and mechanical fastening (screwing, riveting). Cohesion is increased by bringing components together. 5. Coating (Beschichten)
Its strength lies in its logical, scalable structure: six main groups based on material state and behavior, providing a standardized language for a global industry. While the official English version is historical, the standard's enduring structural principles enable universal understanding and application, bridging the gap between design intent and production reality.
The core architecture of DIN 8580 relies on a clean, physical principle: .
: Deep drawing, rolling, extrusion, forging, and sheet metal bending. Cohesion State : Cohesion is maintained . Group 3: Separating ( Trennen )
The standard's core function is to act as a comprehensive "order system." It serves as the foundation on which all other process-specific standards, such as those for forming, cutting, and joining, are built. By adhering to this system, any manufacturing process, whether established or futuristic, can be assigned a unique classification number (ON), making it identifiable for documentation, data processing, and classification purposes.
