Abstract
Using the general methods of A. L. Vorontsov, a mechanical and mathematical study of the fourth and fifth variants of the process of combined extrusion of glasses with a conical bottom was carried out. All necessary design schemes are presented. Calculation formulas have been obtained that make it possible to determine the deformation forces and the magnitude of the plastic deformation areas for each possible variant of the plastic flow of the workpiece metal. These formulas also make it possible to determine which variant of deformation will occur in a particular case, and are necessary for the successful design of this operation. The results of confirming experiments are presented.
