Vibration analysis of a turning tool with passive damping

ABSTRACT: Mechanical vibrations generated during machining can cause many problems in production processes. Vibrations can cause high dynamic loads leading to damage of the machine spindle, the cutting tool or the workpiece. Another unwanted effect of the existence of vibration during the machining process can be a deterioration in the quality of the machined surface. In this paper, a comparative analysis was carried out based on studies of the face turning process with conventional knives and those equipped with passive vibration damping systems. The results show the influence of the implemented vibration damper on the cutting process.

KEYWORDS: vibrations, machining, turning, vibration damping, MES simulations

STRESZCZENIE: Drgania mechaniczne pojawiające się podczas obróbki skrawaniem mogą być przyczyną występowania wielu problemów w procesach produkcyjnych. Drgania mogą powodować duże obciążenia dynamiczne prowadzące do uszkodzenia wrzeciona obrabiarki, narzędzia skrawającego lub przedmiotu obrabianego. Innym niepożądanym efektem występowania drgań w czasie procesu obróbki mechanicznej może być pogorszenie jakości obrabianej powierzchni. W niniejszej pracy przeprowadzono analizę porównawczą na podstawie badań procesu toczenia czołowego powierzchni nożami konwencjonalnymi i wyposażonymi w pasywne systemy tłumienia drgań. Wyniki badań przedstawiają wpływ zastosowanego tłumika drgań na przebieg procesu skrawania.

SŁOWA KLUCZOWE: drgania, obróbka skrawaniem, toczenie, tłumienie drgań, symulacje MES
