Although the interaction between the forming machine and process affects the quality of the finished part significantly, the machine influence is usually ignored in the analysis of the forming process with the Finite-Element-Method. This contribution focuses on this interaction regarding the process of sheet-bulk metal forming. In order to represent the machine characteristics, a hybrid multi-body model of an experimental press has been developed. This model takes into account the machine kinematics and dynamics as well as the elasticity of the press components. In order to validate the machine model the displacement of the press components under load have been determined by means of optical measuring systems. The required three-axial load profiles have been provided by a new developed load device.
