ABSTRACT: This paper presents different constructions of tribometers for determination of friction and tool wear developed in the cutting zone between the cutting tool and the workpiece materials. They are classified as the closed and open tribotesters. Relevant measuring techniques of various process outputs such as cutting forces, tool wear, cutting temperature and heat flux entering the contact surface of the rubbing element are outlined. Some limitations and practical applications are highlighted.

KEYWORDS: metal cutting, friction, wear, tribometer

STRESZCZENIE: W artykule zaprezentowano różne konstrukcje tribometrów do wyznaczania współczynnika tarcia i zużycia narzędzia w strefie skrawania – między narzędziem skrawającym i obrabianym materiałem. Urządzenia te sklasyfikowano jako zamknięte i otwarte tribotestery. Opisano odpowiednie techniki pomiarowe różnych wielkości wyjściowych procesu, takich jak: składowe siły skrawania, zużycie ostrza, temperatura skrawania oraz strumień ciepła wnikający do powierzchni kontaktu trących elementów. Wyjaśniono niektóre ograniczenia i podano praktyczne zastosowania tribometrów.

SŁOWA KLUCZOWE: skrawanie metali, tarcie, zużycie, tribometr
