Abstract
An incremental forging process created on the basis of the modified orbital forging press is investigated in the paper. Development of the finite element model, which simulates metal flow in this process, is the main objective of the work. This model is used in research on possibility of modification of classical orbital forging technology to obtain more efficient process. Due to the novelty of the developed process, the investigation on path of material flow during deformation is of particular interest in this work. A numerical simulation involve subsequent pressing of a set of anvils into the material. Direction of material flow and strain path change, due to incremental character of deformation, are analysed. The results showing flow of metal under the anvils are presented and discussed in the paper. Zone affected by the incremental character of deformation is identified in narrow region in-between subsequent dies. Examples of results of numerical simulations of modified orbital forging press are presented in the paper, as well.
