The paper concerns vibration surveillance during ball end milling of curved flexible details and considering assurance of parameters of a modal subsystem. Here is explained dynamic analysis of non‐stationary vibrating system, from which are separated subsystems: modal, structural and connective. Minimising vibration level by matching the spindle speed to optimal phase shift has been employed. Two alternatives of the approach have been developed. The first one is based on generalised condition of optimum spindle speed and relates to diagnosis of chatter vibration with only one detected frequency. The second approach concerns a few harmonic components having different frequencies. Obtained results of production experiments proved a meaning of the approaches. (© 2009 Wiley‐VCH Verlag GmbH & Co.
