DETERMINING THE IMPACT OF STRUCTURAL FRICTION PARAMETERS IN THE BODY OF AN ASSEMBLED CUTTER ON THE DAMPING OF ITS AMPLITUDE AND SELF-OSCILLATIONS

The paper examines the potential use of dry friction in designing metal-cutting tools to dampen vibration energy. A mathematical model of the self-oscillating system "machine-fixture-tool-workpiece" has been developed and analyzed, considering structural friction within the assembly of the cutting tool. The study has investigated structural friction's impact on the cutter body's self-oscillation amplitude at the cutter tip and the workpiece surface.

Influence of cutting time on types of oscillations during blade processing

Despite many years of research on the impact of vibrations on the quality of manufacturing parts and tool stability during machining, these problems are still relevant. One of the reasons is uncertainty regarding the pattern of occurrence of types of oscillations during mechanical processing and their effect during cutting.
Therefore, the work aimed to determine the patterns of occurrence of types of oscillations during mechanical processing and their effect during cutting.
