Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. In order to achieve an optimal process design, finite element modelling is broadly utilized in industry and research. It is well known that to obtain accurate simulation results, accurate material characterization have to be performed. Although material behaviour of metals under hammer forging conditions are of great industrial interest, few materials have been tested in such high strain rates due to the lack of laboratory machines for high-speed testing. With the objective of addressing that gap, this paper presents a novel automatic forging simulator comprised of an instrumented forging hammer capable of performing high-speed deformations. In this work, results of high strain rate tests performed on the developed hammer were evaluated obtaining promising conclusions.
