The milling processing technology is one of the key technologies in machining parts with the thin wall and complex surface in aerospace. This method can ensure high precision

high-quality and high-efficiency

etc. As one of the important phenomena in milling processing

cutting force directly affects the tool wear

deformation

the processing efficiency and quality of workpiece

and so on. In order to make better use of cutting technology

it is necessary to review and analyze the prediction of cutting forces. As one key method to predict cutting forces

experiencebased milling force models are widely used. Therefore

this paper summarizes the state of art in predicting cutting forces using experience-based models and then analyzes the effect of cutting force coefficient

uncut chip thickness

tool runout

and deformation on cutting force. In order to provide useful reference

the future research direction of this field is finally discussed.
