The article discusses the production of cylindrical hollow workpieces with different cross-sections along the height. The difference in cross-sections is ensured by crimping. During the crimping, the ends of the blanks are thickening. The operation under consideration is carried out in a hot state with local heating of the workpiece elements with a slow movement of the tool. It occurs due to the material grade of the workpiece, which is very demanding in terms of the deformation conditions. Simulation of the studied combined process has been carried out, during which the influence of the parameters of the main operations (deformation rate, heating parameters, friction) on the possibility of obtaining products with specified geometric characteristics has been established.
