Thermo-Mechanical Investigation of Spinning Process

One of the old forming processes in which there is ability to produce empty parts with central symmetrical axis under acting of local and circular force is called spinning process. In cases that there is no possibility to use the process of deep drawing due to size or complex structure, spinning is a good substitute process. In metal forming processes such as spinning, temperature is one of the important parameters which must be investigated. Regarding investigation of thermo-mechanical simultaneous spinning process, no work has been done to date while some studies have been done on mechanical analysis of spinning process. In this study, the finite element method and an experimental test are used for simulation and validation of spinning process parameters for aluminum sheet. The simulation is used for two different shapes such as hemisphere and semi-conic. By comparison of numerical and experimental results it is observed that these results have suitable convergence.
