“…The first works which devoted to numerical modeling of rolling in skew-roll piercing mills were based on 2D finite element method (FEM) models in the 1990s [3] . Recently many authors had tried 3D modeling of the piercing process [4][5][6][7] .…”

The finite element method (FEM) is used for simulation of the tube piercing process in Mannesmann mill. The numerical model is described with taking into consideration thermal phenomena in metal during forming. The simulated results visualize dynamic distributions of mean stresses, temperature, velocity and shear stresses, especially inside the workpiece. On the basis of the basic parameters, the phenomenon in the piercing process is analyzed. The model is verified by comparing the values of calculated force parameters of the piercing process and those measured in laboratory conditions.

“…It is performed using rolls with helically wound wedges on their perimeter. The first studies on numerical modeling of helical rolling were conducted in the 1990s; they concerned a piercing process for thick-walled tubes and were based on two-dimensional FEM models [13]. However, given the nature of metal flow in these processes, they should be simulated in a threedimensional (3D) state of strain.…”

Abstract. This paper presents the results of a numerical analysis of a helical rolling process for producing a 25 mm diameter workholding bolt using multi-wedge helical tools. The numerical modeling was performed by the finite element method (FEM) using the commercial simulation software Simufact.Forming v. 12. The modeling was performed in a three-dimensional state of strain and included a full thermal analysis. As a result, the changes in workpiece shape as well as the distributions of strains, temperature, damage, loads and torque were determined. The numerical results confirm that workholding bolts can be produced by multi-wedge helical rolling.

This paper presents the research results of the balls rolling process according to the conventional and modified methods of rolling. Theoretical analysis was carried out by using numerical methods based on the Finite Element Method. The Simufact package version 10.0 were used for calculation. Simulations of balls rolling were carried out under conditions of 3D state of strain, taking into account the effect of thermal conditions occurring during forming. The study of the achieved results showed that the best rolling process parameters were obtained for the modified method, in which the feed material is heated up to 1150 °C. In this case, the rolling parameters such as: rolling force and torque as well as tool wear reached the smallest values.
