5-axis milling operations are widely spread in contemporary machinery, especially while processing the turbine blades or other free form surfaces. As the vibrations inevitably arise during milling process they can considerably impair the machined surface quality. Therefore it is necessary to select appropriate milling parameters applying the developed numerical models of 5-axis milling dynamics. А new algorithm is considered in h paper. It takes into account the dynamic characteristics variation while stock removal and is embedded into the whole numerical model. The analysis of stock removal influence on eigen frequencies and eigen modes of free-formed work piece vibrations is also considered in the paper.
