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.
