EFFICIENCY OF KINEMATIC CHIP BREAKING ON A CNC LATHE

When turning many materials, especially such as high-alloyed steels and a some of non-ferrous metal alloys, long continuous chips are usually formed which clutter the working area machine tools dangerous for workers. One effective reliable methods chip breaking during is vibration cutting, when uniform motion cutter relative to workpeace process superimposed with an additional cutter. The use oscillating movements in direction longitudinal feed most turning. To ensure necessary amplitude-frequency range oscillations, toolholder elastic part form machined spring cross slot configuration directional stiffness. equipped mechanism part, receives movement from drive tool spindle tool. development research mathematical model cutting system determined conditions under takes place regardless modes properties processing material. conducted experimental studies confirmed effectiveness proposed elements turning.
 Key words: breaking, simulation, configuration.
