The cutting force is one of the main factors that influence the processing quality of fiber-reinforced polymer composites (FRPs). However, since the material removal mechanics of composites are quite different from those of metals, the cutting mechanisms of metals cannot be directly used for orthogonal cutting of composites. This paper aims to develop a novel force prediction model without the need to run any experiments. The deformation of fiber and the support of surrounding matrix are analyzed based on the minimum potential energy principle and the dynamic equilibrium. A force prediction model of FRP cutting is obtained for fiber orientations ranging from 0 to 90° + γ. The relevant experiments conducted showed the validity of the proposed model. The influence of rake angle and clearance angle on cutting force is analyzed.
