| Abstract Scope |
The primary purpose of this research is to investigate the influence of axial feed-rate on shape and thickness changes in multi-pass, mandrel-free tube spinning for producing a hemispherical shape at room temperature. The target shape is formed experimentally by 7 spinning passes from annealed, pure aluminum AA1070-O tube. The experiments are conducted with three different axial feed-rates i.e. 2, 5 and 7.5 mm/rev., and interrupted after spinning passes 2, 4 and 7. In every experiment, the tube buckled at some point during the process, due to the high axial-feed. It was also found that decreasing the axial feed-rate generates higher elongation and lower thickness change. A 3D elastic-plastic finite element (FE) model of the multi-pass tube spinning process is described. The mechanisms of influence of the axial feed-rate on axial buckling, tube elongation and thickness change are discussed through the comparison between experimental and simulation results. |
