Multivariate orthogonal experiment of ultra-high strength steel 30Cr3SiNiMoVA were designed to investigate the effects of cutting parameters on the machinability. Aimed at the milling force and the surface roughness, the milling parameters were optimized. Both cutting force and surface roughness formulas were obtained by the nonlinear regression method. And then, milling parameters were optimized by integrating the experiment results of milling forces and surface roughness. This result has certain guiding significance to choose milling parameters for machining ultra-high 30Cr3SiNiMoVA.
