【Abstract】 Regression orthogonal design and single factor design are applied to cutting force simulation in high speed turning of high strength aluminum alloy with PCD tool by DEFORM-3D. The prediction model between cutting force and cutting parameters is established,and the reliability of the model is verified by analysis of variance. The effect of cutting parameters on the cutting force and its mechanism are studied by the method of single factor simulation of cutting parameters.The effect of tool parameters on the cutting force and its mechanism are studied by the method of single factor simulation of tool parameters. The results provide a theoretical basis for the optimization of process parameters of high speed turning high strength aluminum alloy with PCD tools.更多还原
