One possibility to increase the performance of machine tools is the achievement of higher accelerations and jerks of moved slides and stands. By this the energy consumption and machining-costs can be optimized. Nowadays machine tool structures are already optimized and further enhancements are not easily achieved. The paper deals with the mechatronic system optimization of a large-scale HSC- and HPC- portal milling centre for e.g. forming tools. This includes the identification of dynamic limiting structures and the following optimization by mechatronic system-monitoring. From process necessities a machining-time reduction by higher accelerations and improved process stability is intended. The system parameters where achieved by the implementation of a redundant axis and the usage of up-to-date lightweight design by reinforced plastics.All over the design phase the structure was constantly monitored regarding their dynamic behaviour. Furthermore a model was used – using a state space – to prejudge the machining time for a concrete example cycle. So even before any physical prototype exists the mechatronic system-behaviour of the machine tool was pre estimated using a virtual mechatronic model. This allows for a virtual product design with a new and improved quality of safety in achieving the pre-defined goals.
