Original abstract

The paper deals with a study of 2D surface parameters, Coulombs coefficient of friction and cutting/forming performance of selected PVD coated HSS taps when machining of carbon steel C45 and forming of hardened steel 42CrMo4V. The main attention is focused on the analysis of physical parameters of loading (torque moment, total energy and specific energy) of the taps measured with the pieso-electrical dynamometer Kistler 9272. The relation between the quality PVD coatings and their effects on the quality of machined thread surfaces and tool life of the taps and the tribological and surface parameters has been found. The results showed a safe and stabilized cutting and forming with excellent quality of threads for HSSE with the TiN/DLC coating.

Příspěvek se zabývá studiem 2D povrchových parametrů, Coulombovým koeficientem tření, řezivostí vybraného PVD povlaku na HSS nástroji, při obrábění uhlíkové oceli C45 a tváření kalené oceli 42CrMo4V.Hlavní pozornost je zaměřena na analýzu fyzikálních parametrů zatížení (krouticího momentu, celkové energie a specifické energie) závitníků, měřených pieso-elektrickým dynamometrem Kistler 9272. Analýzy PVD povlaků, jejich dopady na kvalitu opracované závitové plochy a životnost závitníků, tribologické a povrchové parametry povrchu. Výsledky prokázaly bezpečné a stabilizované řezání i tváření s vynikající kvalitou závitů HSSE s TiN / DLC povlakem.
