The high-speed precision milling experiment of quenched 30CrNi2MoVA high-strength steel is carried out by using the orthogonal experimental scheme of three factors and three levels,and the influence law of milling parameters on milling force and the high-speed cutting mechanism are obtained.The exponential regression model is established for the ex-perimental results of each milling force and its significance is analyzed by variance analysis of the linear model of milling resultant force.The significant analysis results of milling parameters for the change of milling resultant force is carried out,in which the axial cutting depth is the most significant,followed by the feed per tooth,and the cutting speed is the least sig-nificant.Combining Taguchi method with range analysis method,single objective parameter optimization is carried out by milling resultant force,and the same optimal milling parameter combination is obtained.Through the calculation,it is proved that the predicted value of Taguchi prediction method is consistent with the experimental value.
