Original abstract

This paper deals with hard turning of steel 100Cr6 with a hardness of C. Surface integrity expressed in terms ofwhite layer thickness is studied as a function of tool wear and corresponding thermo-mechanical load of the machined surface. Total force is decomposed into components associated with the chip separationFγand thecomponentFɑ, which is associated mostly with the flank wear land. The results of experiments show that normaland shear components of the forceFɑ, increase progressively with the developedflank wearVBand correlatesignificantly with the white layer thickness. Furthermore, tool wear is also strongly dependent on the insert rake geometry, which contributes to the cutting force component of Fγ associated with the chip separation. For this reason, the chip formation depends on the progress of the tool wear.

Czech abstract

Tento článek se zabývá tvrdým soustružením oceli 100Cr6 s tvrdostí C. Integrita povrchu vyjádřená jako tloušťka bílé vrstvy je studována jako funkce opotřebení nástroje a odpovídajícího termomechanického zatížení obrobené plochy. Celková síla je rozložena na komponenty spojené se separací třísek F a komponentou Fɑ, která je spojena většinou s opotřebením boku. Výsledky experimentů ukazují, že normlandské smykové složky síly Fɑ se postupně zvyšují s vyvinutým bočním opotřebenímVBand koreluje významně s tloušťkou bílé vrstvy. Kromě toho je opotřebení nástroje také silně závislé na geometrii shrnovače břitové destičky, což přispívá ke složce řezné síly Fy spojené se separací třísky. Z tohoto důvodu závisí tvorba třísky na průběhu opotřebení nástroje.
