2003-8-4an equivalent diameter for end mill based on FEA in order to be able to use beam equations for deflection calculations, which eliminate stiffness measurements for each tool. Schmitz 22, 23 used substructuring methods to predict the dynamics of tool holder-end mill
A dynamic model for a ball-end milling process that includes the consideration of cutting force nonlinearities and regenerative chatter effects is presented. The nonlinear cutting force is approximated using a Fourier series and then expanded into a Taylor series up to the third order. A series of nonlinear analyses was performed to investigate the nonlinear dynamic behavior of a ball-end ...

Structural modeling of end mills is crucial for predicting deflections and vibrations in milling processes. End mill geometry is very complex which makes the use of simple beam models inaccurate. Stiffness and frequency response function FRF measurements need to be performed to identify the static and dynamic properties experimentally.
