Originální abstrakt

This paper deals with the possibility of elimination of self-excited oscillations by changing the thickness of chips. These oscillations occur between the tool and machining area during the cutting process without any outer influence. This results into degradation of the machined surface, the geometric accuracy and the noise. A model of cutting process (Eq 1,2) is constructed using the theory of regenerative principle. The model is used to derive analytical formulas for gains of two simple controllers (Fig 2) which control a piezoelectric compensator of the cutting force. The compensator changes the position of cutting tool against the machined surface. This changes the thickness of chips.

Český abstrakt

Tento článek se zabývá možností odstranění samobuzeného kmitání změnou tloušťky třísky. Tyto kmitání se oběvuje mezi nástrojem a obráběnou oblastí bez vnějšího působení. Výsledkem je horšená kvalia obráběného povrch, snížená geometrická přesnost a hluk.
