Abstract: The hardness and wear resistance of hardened steel are high. It is widely applied in the field of automobile and die manufacturing field. In order to get a reasonable cutting plan, the influence of cutting parameters on milling force and temperature is explored in the process of high speed milling of hardened steel. High speed milling experiment with different machining parameters is carried out and centre composite response surface method is applied. The regression model of cutting force and cutting temperature are established in the process of high speed milling of hardened steel. The significance of the milling parameters on the force and temperature under the interaction and its reasons are analysed. Analysis of variance is performed to evaluate the significance of regression. It can effectively predict the milling force and milling temperature in the process of high speed milling of hardened steel. It provides the basis for the reasonable choice of cutting parameters. From the processed surface quality to verify that cutting parameter is selected based on prediction model and the significant analysis of milling force and temperature is more reasonable.
