For example, the main group 2, forming, is broken down into subgroups based on the dominant stress condition. The process of "deep drawing" would have an ON like 2.4.X, placing it clearly within the hierarchy. This system allows for precise documentation, process planning, and data exchange in manufacturing IT systems.
Separating alters the shape of a workpiece by locally destroying its material cohesion, typically resulting in the generation of chips or scrap. din 8580 english pdf top
This group involves creating a solid body from a shapeless material (liquid, powder, or gas). Key Processes:
Dividing processes intentionally change the cohesion (the internal bond) of a workpiece. This is mainly achieved by (cutting or shearing) or removing chips, which is detailed further in DIN 8589 (Manufacturing processes chip removal). Separating 4
This unique group does not focus on changing the geometry of the part. Instead, it alters the internal structure of the material—such as its crystal lattice or molecular arrangement—to achieve specific mechanical or physical properties. Cohesion/internal structure is rearranged.
For instance, if you trace , its classification path looks like this: Main Group 3: Trennen (Subtracting) Modifying Properties 1
