On the basis of calculations the quantitative and qualitative effect of the sheet thickness, the radius of the rim and the height profile on the power parameters of the process are installed. Finite-element model was developed to determine the legitimacy of the assumptions and the accuracy of power parameters calculation. As a result of solutions analysis the identified levels of strain and stress, as well as the nature of the loads increase. Profiling force calculation error does not exceed 6.7%.
