[Abstract]:Based on the adhesive friction theory, an empirical model between the local friction factor and the normal stress and relative slip rate of the contact surface was established. The experimental method was used to analyze the local friction phenomenon between the cutter and chip interface in the right angle cutting process. The design of the model was carried out. The experiment can provide the same relative slip rate and normal stress condition as the actual cutting. The experimental results show that the friction coefficient decreases with the increase of the normal stress and the relative slip rate at a certain range of normal stress and slip rate.
