Abstract
Metal spinning is an incremental sheet metal forming technique used to manufacture axisymmetric, thin-walled parts, ranging from rocket nose cones and jet engine components to automotive connecting rods and everyday items like ventilation ducts and kitchenware. A primary challenge in this process is the occurrence of wrinkling, especially when forming complex geometries. Although manufacturers often mitigate this defect through methods such as flanging or constraint spinning, determining the optimal spinning conditions typically relies on trial and error. This study aims to predict wrinkling in metal spinning using numerical simulations that are validated by experimental trials. Two common computational acceleration techniques, such as increasing the loading rate and applying mass scaling, are examined for their impact on material behavior and defect formation. Our comprehensive analysis shows that when both the mass scaling factor and loading rate are kept below a threshold of 20, the simulation results closely mirror experimental observations. This strong correlation is attributed to the simulations' effective capture of the dynamic and inertial behaviors inherent in the spinning process. Overall, these findings emphasize the need for careful control of loading rate and mass scaling to preserve simulation accuracy, as excessive increases in these parameters lead to notable deviations from real world behavior.
