Abstract

The invention discloses a milling parameter optimization method suitable for surface machining of a thin-walled workpiece, which comprises the following steps: selecting milling parameters, establishing a factor level table by adopting a central composite design method, and constructing a mathematical model of surface roughness and residual stress; solving the mathematical model by adopting an improved non-dominated sorting genetic algorithm, and selecting an optimal solution by adopting a TOPSIS method based on an absolute ideal point; finally, verifying the effectiveness of the method through experimental processing results. Experiments prove that the relative error between the optimal milling combination solved through the method and the predicted value is small, and the method has certain reference value and social and economic benefits.
