In high speed ball-end milling hardened steel, the increase of hardened steel hardness and cutting efficiency make cutting loads changing, and fuzzy and uncertain properties exist in evaluating cutting vibration and machining surface quality. To explore the means for high efficiency and precision machining hardened steel, carried out the experiment of high speed ball-end milling hardened steel, and acquired behavior data of high speed milling characteristic and influencing factors. Founded the model of high speed ball-end milling behavior characteristic using grey system theory, acquired the behavior sequence of high speed ball-end milling hardened steel. Accomplished incidence analysis of high speed milling characteristic, and proposed the solution to high efficiency and precision machining hardened steel. Results indicate that the increase in cutting efficiency makes workpiece vibration and the increase in surface roughness. The influence of the row spacing on the vibration in feed direction is more remarkable than the vibration in row spacing direction. Grey incidence matrix of high speed ball-end milling characteristic reveals the interaction level of characteristic and influencing factors. Increase in rotational speed and row spacing, and decrease in feed per tooth and inclination angle of cutter can restrain availably the vibration in high speed ball-end milling hardened steel, and obtain higher cutting efficiency and surface quality.
