To solve the problem of missing constitutive model of A100 steel material
a backward identification method of the Johnson-Cook(J-C) constitutive model parameters based on experimental design is proposed. According to the sensitivity analysis results of A100 steel and the reference value
conduct the finite element simulation of the milling process
establish the regression prediction model of the constitutive parameters on the milling force
so as to transform the parameter identification problem into the minimum problem of the solution function
and improve the particle swarm optimization algorithm with linear decreasing weight of A100 steel J-C constitutive model with good simulation accuracy in large milling speed level interval. Compared to the milling experiment results
the maximum error of the milling force simulation is only 11.31%. The accuracy of the constitutive parameters and the feasibility of the backward identification method are verified.
