ABSTRACT
The paper deals with the concept of solid railway axle rolling using tools (rolls) in which the forming zones of individual workpiece steps are separated. Two types of tools were analysed, which were characterised by flat (typical solution) and convex (novel solution) forming surfaces of the wedge. Using the software Forge® NxT, simulations were performed of the rolling processes of the rail axle. Distributions of temperature, damage function, effective strain as well as force and torque courses were analysed. The results showed that it is possible to produce solid railway axles using the CWR method and confirmed the use of tools with a convex forming surface.
