Method to Calculate Oscillatory Die Volumetric Deformation Process Specific Parameters

Abstract

Deformation process by using an oscillatory die is more convenient than conventional volumetric forming, because it requires, to obtain the same piece, a smaller manufacturing force (in the conditions of a floating contact surface) and allows higher deformation degrees, due to a slower cold hardening process. The paper suggests a calculus method to evaluate the forming force and the torque applied to oscillatory shaft.
