Abstract
Dynamic models of machine tools can be used to predict their dynamic behavior in machining simulations. In a geometric-physical simulation a dynamic model comprising damped harmonic oscillators can be used to represent the frequency response functions (FRF) of the machine. The axis positions of milling machines change during machining and, thus, the FRFs vary. Therefore, the FRFs have to be determined at different locations in the workspace. Due to practical reasons, the number of measurement positions is limited. A method for interpolating the modal parameter values of the dynamic model is applied and evaluated.
