Paper Title:
Dynamics Characteristics of High Speed Ball-End Milling Cutter for Machining Hardened Steel
  Abstract

In order to depress cutter vibration caused by high hardness and periodic change of cutting force in high speed milling complex surface, investigated the modal characteristics of ball-end milling cutter through the modal analysis and transient analysis. Using the models of dynamic cutting force and cutting vibration, acquired dynamics characteristics of high speed ball-end milling cutter by the spectrum analysis of dynamic cutting force, simulation analysis of cutting vibration and experiment of high speed milling hardened steel. Results indicate that high speed ball-end milling energy concentrates in few special frequencies, the rotational speed and the numbers of cutter teeth determine the fundamental frequency. High speed ball-end milling cutter easily makes radial bending vibration by the lower modal characteristics, the overhang and inclination angle of cutter affect its dynamics characteristics significantly, and the modal parameters and vibration model of cutter acquired by step response method have higher credibility.
