【 摘 要 】

Calculation formulas of general type and the developed mathematical model of the direct extrusion process are presented, which makes it possible to determine the force mode of deformation. The examples of calculations and graphs showing the possibility of determining the optimal tool geometry and determining the amount of decrease in deformation force when using a die with a movable matrix are given.
