The use of numerical modelling allows us to shorten the time for development of new technologies and to optimise the existing ones in view of final material properties. The paper presents the modelling of shape rolling of 5 mm round bars in diamond and oval grooves. Modelling scheme consists of three stages. The first stage is a development of rolling schedule, which is based on finite-element method simulations. The schedule design begins from the last pass. The paper presents the schedule developed for the last six passes. Then, in the second stage, finite-element method simulations were fulfilled in the proper rolling sequence. The aim of this stage is obtaining the thermomechanical parameters of the process. These parameters are transferred to frontal cellular automata model that takes into account the deformation and simulates microstructure evolution. Some results of finite-element method and frontal cellular automata modelling are presented in this paper. [ABSTRACT FROM AUTHOR]
