Mathematical modeling of power spent in face milling taking into consideration tool wear

In this paper, a mathematical model has been developed for the main drive power expended in face milling taking into consideration the wear of teeth on the back surface of the tool. The model considers the conditions of cutting, the size of the flank wear of the cutter tooth on the back surface, the properties of the material, and the geometric parameters of the tool. The paper has established the adequacy of the mathematical model of the main drive power expended in face milling. By monitoring the power of the main drive of modern CNC machines, it is possible to control the conditions of face milling in the process of change in the size of the flank wear of the cutter tooth on the back surface.
