Original abstract
The paper deals with modeling of self-excited oscillations generated during a machining process. These oscillations are generated between a cutting tool and a work-piece without any outer influence. This results in decreasing quality of a work-piece surface as well as decreasing geometrical precision of the surface. The secondary effect is increased level of noise emissions. Due to these problems, and in order to facilitate further increase of the machining preciseness and cutting velocities, it is necessary to minimize the self-excited oscillations of the cutting tool as much as possible. This task is solved worldwide by many scientific teams but a sufficient solution for industrial applications was not proposed so far. There are several theories dealing with the problem of self-excited oscillations. The solution of their elimination developed at BUT FME is based on the "reproduction principle"
Czech abstract
Tento příspěvek se zabývá modelováním samobuzených kmitů vznikajících při obráběcím procesu. Tyto kmity vznikají mezi řezným nástrojem a obráběnou plochou bez vnějšího zásahu. Jejich půsebením dochází ke snižování kvality povrchu a geometrického tvaru obráběné součásti a dále se projevují hlukem. Existuje několik teorií popisujících vznik samobozených kmitů jako například tzv. "regenerativní princip", na kterém je založeno řešení eliminace samobuzených kmitů vyvíjemé na FSI.
