The paper concerns vibration surveillance during ball end milling of curved flexible details. Here is explained dynamic analysis of non‐stationary vibrating system, from which are separated subsystems: modal, structural and connective. An assessment of coincidence of the calculation model results with those from investigation on milling machine is performed. Ball end milling of flexible details is observed very frequently in case of modern machining centres. It is obvious that tool‐workpiece relative vibration plays principal role during cutting process. The most important task is to create a FE‐model of machined flexible detail and obtain its good correlation with the results of experimental modal analysis. (© 2009 Wiley‐VCH Verlag GmbH & Co.
