Originální abstrakt
The article deals with design of the controller for elimination of self- excited oscillations during machining. These oscillations are generated between a cutting tool and a work-piece surface and lead to decreased quality of the ma- chined surface as well as decreased geometrical precision. The secondary effect is increased level of noise emissions. In general, the self-excited oscillations nega- tively affect the working productivity of metal cutting machines and inhibit its growth. The design of the controller is based on a model of the cutting process which works with so-called regenerative principle of the self-excited oscillations generation and is based on the variable chip thickness. The model itself serves to derivation of the controller gains. A piezoelectric compensator of the cutting force is controlled by the designed PSD controller. The compensator changes the posi- tion of the tool against the machined surface thereby changing the chip thickness.
Český abstrakt
Tento příspěvek se zabývá návrhem regulátoru pro eliminaci samobuzených kmitů obráběcích strojů. Tyto oscilace vznikají mezi obráběcím nástrojem a obráběnou plochou a snižují její kvalitu a geometrickou přesnost. Sekundárním efektem je zvýšená hladina hluku. Návrh je vytvořen na základě modelu řezného procesu pracujícího s regenerativním principem samobuzených kmitů a s proměnnou tloušťkou třísky. Piezoelektrický kompenzátor síly je řízen pomocí PSD regulátoru. Tento kompenzátor mění pozici nástroje vůči obráběné ploše a tím mění tloušťku třísky.
