Degree of forming
The degree of forming is a parameter indicating the extent of plastic deformation of a material. It describes the extent to which the dimensions of a workpiece change during a forming process.
The degree of forming is closely related to the material properties. In cold forming, as plastic deformation increases due to work hardening, the flow stress required for further deformation generally also rises.
Degree of forming in the design of forming processes
The degree of forming is related to work hardening and the flow stress required for further forming. Among other things, this influences the forming forces that occur. These must be taken into account when designing the tools and selecting suitable forming machines.
In multi-stage forming, the required change in shape can be distributed across several forming stages. This allows the material to be gradually brought into the desired final geometry, whilst specifically taking into account the stresses within the individual forming stages.
