The invention relates to the technical field of metal cutting machining, and particularly discloses a cutting force modeling method for a chamfering blade knife. The cutting force modeling method includes the following steps of: acquiring geometric parameters, cutting parameters and material parameters of the knife; calculating shear stress and process variables according to the geometric parameters, the cutting parameters and the material parameters of the knife; calculating a cutting force of a sharp knife according to the process variables; obtaining a correction function of the chamfering blade knife according to the cutting force of the sharp knife; and performing modeling calculation according to the correction function of the chamfering blade knife and the cutting force of the sharp knife to obtain the cutting force of the chamfering blade knife. The cutting force modeling method for the chamfering blade knife provided by the invention can implement calculation of the cutting force of the chamfering bl
