Notes:
The temperature effect is significant on the metal forming processes; for the quality ofproducts and the tools life are extremely affected by it. This paper investigates the thermal effects onthe conventional spinning process by the explicit finite element method with transient heat transferconditions. The governing equation is based on the updated Lagrangian formulation, the largedeformation theory, and the principle of the conservation of energy. The energy terms in this studyinclude the plastic strain energy, the frictional sliding energy, and the heat transfer energy. The energyand temperature distribution of the circular sheet, on the varying boundary conditions of the heattransformation, are discussed in detail. Furthermore, the various mesh types are examined in thesimulations. With the application of the mass scaling factor technique, the full history of spinningprocess is performed successfully. The main benefit of the proposed model will save the tremendouscosts in the die designing and the experimental works. The parameters and techniques using in thenumerical model are helpful for the design of forming process and the coupling thermal-mechanicalanalysis
