42CrMo steel is a typical high strength alloy structural steel, which is widely used in the cross sec-tion of the requirement for high strength. But parts’ processing quality and service life are drasti-cally affected due to excessive cutting force, cutting temperature, no broken chip and tool wear in the process of milling. In this paper, orthogonal experiment method for milling high strength 42CrMo steel experiments is carried out. The basic characteristic of cutting force is studied in mil-ling process of the high strength 42CrMo steel. The radial cutting depth, the axial cutting depth and each tooth feeding effect on cutting force are analyzed. And using the least squares regression analysis, the empirical formula milling force was obtained to provide reference for design and cutting parameter selection.
