Short summary

In this paper, data-driven and genetic algorithms are combined to optimize the parameters of the Jonson–Cook model and improve the simulation accuracy. Experiments verify the accuracy of the model, and the influence of cutting data on the residual stress of the machined surface is discussed, which provides suggestions for the cutting process and tool design.
