The paper presents computer modelling and experimental results of investigations on pushing through a conical die process of round bars. The calculations were carried out using the commercial code QFORM-2D, based on the Finite Element Method (FEM). The investigations involved the use of circular sectioned S355 (1.0577) steel segments of rods with diameter of 9 mm. Result of calculations of pushing through a conical die process were validated against experimental data in terms of changes in forces for different elongation factors (lambda(1) = 1.24, lambda(2)= 1.37, lambda(3) = 1.57). The aim of the paper is to compare the experimental and computer modelling changes in forces for different degree of deformations. The results of investigations into pushing through a conical die process might be used as guidelines to develop a technological process for industrial practice.
