Abstract in different language: The case study results in Fig. 1 showed that the application of composite materials to the transverse beam increased the dynamic compliance of assembly by 21 % with a slight frequency increase. Therefore, the design change would reduce the machine productivity. On the other hand, the application of composites to the spindle ram reduced the dynamic compliance by 13 % with a slight frequency shift. This would help the machining productivity, the question is if the higher material costs of composites can be justified by this improvement of the dynamic behaviour. The simulation model demonstrated a capability for predicting the dynamic behavior of the structural parts assembly using the modal damping of structural materials and modified damping in connection interfaces. Experimental verification will be the part of future works.
