DETERMINATION OF THE DOSE OF MECHANICAL ENERGY REQUIRED FOR MILLING ALUMINUM ALLOY CHIPS IN A PLANETARY MILL

The paper presents the results of modeling the motion of milling bodies in the working chamber of a planetary mill at different processing speeds. Quantitative estimates of the effect of processing speed on the kinematic characteristics of the motion of milling bodies, the number of collisions, the total energy loss during collisions and the average specific loss of collision energy are obtained. Changes in these parameters for «body-body» and «body-camera» collisions have been studied. Experimental studies have been conducted to study the effect of speed, machining time in a planetary mill and the ratio of chip mass to the mass of milling bodies on the transformation process of chip material. By comparing the calculated and experimental data, the minimum dose of mechanical energy was determined, which ensures the formation of flake-like particles and powder from the chip material.
