By altering the cutting edge profile, edge preparation can increase the stability of the cutting process, extend the tool life, and improve the machined surface quality. Herein, a theoretical model of cutting force based on milling tool edge preparation is established according to metal cutting theory and material constitutive equations. The influence of edge radius, milling speed, tool feed, cutting depth, and rake angle on the cutting force are investigated. The results of simulations of the tool milling force of a cemented carbide tool milling 45 steel were performed in the metal cutting modeling software AdvantEdge. Theoretical values of cutting force and torque are compared corresponding values obtained through the milling simulations and cutting experiments, respectively, to verify the proposed cutting force model based on edge preparation. The research results provide the basis for realizing the tool edge preparation effect, the high speed and the high efficiency cutting. [ABSTRACT FROM AUTHOR] |
