The fundamental principle of groove spinning forming lies in the transfer of metal volume, adhering to the principle of volume invariance in plastic deformation. Essentially, groove forming is achieved through material flow along the tube wall, which results in variations in wall thickness. This change in thickness is a characteristic of flow forming. However, unlike conventional flow forming, where the material predominantly flows axially, groove spinning forming also induces a radial material flow due to the applied pressure.
