This article describes the creation of a holistic modeling of a machine tool using a multi‐body‐systems approach with an integrated flexible body. This lower order model is validated by a detailed finite element model and its eigenvalues are improved by a model‐updating algorithm. The improved model is used for investigation of the machine vibration during the cutting process and the prediction of chatter. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
