“…The simulation involved the modeling of a process for forming 80 mm diameter balls from a rail head described by a length of 92.5 mm. The authors of this paper have considerable experience in performing numerical modeling of different metal forming processes, and the applied simulation software, Simufact.Forming, enables obtaining results which show a good agreement with experimental findings [10][11][12][13][14][15].…”

The paper describes a new method for forming grinding media balls from scrap rail heads. This forming method involves the following operations: cutting the rail head to the desired length combined with lateral pressing of the produced workpiece; flashless die forging and sizing of balls in a helical impression. The proposed method was verified by numerical simulation which involved the modeling of a forming process for producing 80 mm diameter balls. As a result of the modeling, it was possible to examine the changes in the workpiece shape during each forming operation, the variations in loads and torques, as well as the distribution of temperatures enabling performing another forming operation, i.e. quenching. The results confirm that the designed method can be used to produce balls.

This software has been used by the author and the others researchers to investigate skew, cross and ring rolling processes [8][9][10][11][12][13][14], and the numerical results showed good agreement with experimental results. The results will be used when designing a laboratory stand for skew rolling which will be constructed at the Lublin University of Technology in the near future.…”

Skew rolling is a metal forming technique which can be used for producing stepped axles and shafts. This paper investigates seventeen cases of rolling at varying process parameters by the finite element method. As a result, it is possible to determine the effect of the forming angle α, skew angle Θ, linear velocity of the chuck, v, billet temperature, T, rotational speed of the rolls, n, reduction ratio, δ and friction factor, m, on axial load (acting on the chuck), radial load (acting on the roll in the radial direction) and torque. The results will be used when designing a laboratory stand for skew rolling which will be constructed at the Lublin University of Technology.

“…Forming software. This software was fre-quently used by the author and other researchers for the analysis of cross and helical rolling pro-cesses [12][13][14][15][16][17] and the results from calculations were in good compatibility with the results of experimental research. It was assumed in calculations that the behavior of the formed material (steel of R200 type), in hot metal forming conditions, is described by the following equation: (1) where: σ p -yield stress, MPa; φ -effective strain; φ̇ -strain rate, s…”

This paper presents an innovative helical rolling process of balls destined for mills manufactured from a scrapped rail head. In this process, helical rolls are applied, whose construction allows obtaining a cylindrical bar, and later balls are formed from this bar in the further stage of the process. It is advised to precede the rolling process by side pressing leading to increase of billet material shape compactness. Verification of the assumed solution correctness was made using numerical simulation, with the application of Simufact.Forming software.
