In this paper the deformation force of the forging process in step-wedge strikers was studied. At the first stage, the study of the deformation force using computer modeling in the Deform-3D software package was carried out. At the second stage, an experimental study of the deformation force during the broaching of workpieces in step-wedge strikers using thermometry was carried out. It is established that the experimental results have a high convergence with the simulation values. The increasing level of difference in results is associated with heat losses during intermediate operations, which are usually ignored during modeling.

Using computer simulat ion in the environment of the DEFORM-3D appl icat ion package, a virtual ful l factorial experiment was conducted on the process of producing long length workpieces from low -al loyed chrome bronze by equal channel angular pressing (ECAP) using the Conform scheme. During the virtual experiment, an assessment was made of the inf luence of independent factors (impel ler rotat ion speed, number of cycles, and temperature of deformat ion treatment) on the response parameter — deformat ion force. As a resul t of the experiment , a regression equat ion was obtained, a variant of solving the opt imizat ion problem wi th determining the numerical values of the accepted independent factors was presented, an d their inf luence on the response parameter was analyzed.
