STRESZCZENIE: Drgania samowzbudne są jednym z najważniejszych ograniczeń wydajności obróbki i jakości wyrobu gotowego. Dobór prędkości obrotowych pozwala na ograniczenie tych drgań poprzez zakłócenie efektu regeneracji śladu. Testowanie i dobór właściwych parametrów może być znacznie ułatwione dzięki obróbce wirtualnej.

SŁOWA KLUCZOWE: drgania samowzbudne, symulacja numeryczna, wirtualna obróbka

ABSTRACT: A self-excited vibrations (chatter) are one of the most important limitation in machining performance and quality of finished parts. Selection of stable spindle speed can suppress self-excited vibrations occurrence, by disrupting regenerative effect. These technic can be tested during process planning via virtual machining.

KEYWORDS: self-excited vibration, numerical simulation, virtual machining
