Abstract

Issues of creating a mathematical model at investigating the average stress in a brass workpiece at processing by a single-toothed corundum milling cutter are studied. An attempt is made to combine the cutting force, theoretical elements of plasticity and the dependences of the experimental data in one module. The proposed model allows to determine the average stress and average temperature of cutting. The distribution of the average stress in the cutting zone of the material to be treated at free cutting is carried out. The cutting temperature is calculated by the formula obtained on the basis of the energy conservation law, also allowing to calculate the average stress in the cutting zone, depending on the temperature and cutting conditions.
