Feature Analysis for Milling Force of Three-Edge End Mills


Article Preview

In order to obtain the features of force for three-edge end mills in normally milling, an equation of milling force in Y direction was built based on the presumption that the forces of every edge are not equal, and its simulation waveforms in time domain was analyzed, the force of Y direction was found to present different spectral features under different radial depth of cut or ratio of radial force to tangential force. Milling experiments were done in a three-axis CNC machine, the features of measured force meets the results of simulation analyze. Study results indicates that the force in slot milling contains a rather great sub-component with spindle rotational frequency, while in partial milling the main sub-component is that with tripler of spindle rotational frequency. This conclusion can be used as the reference basis in judging failure of mills.
