New aspects of metrology of frictional behaviour in metal cutting *

STRESZCZENIE: This paper introduces a method for a fast identification of friction and heat partition models in cutting. Based on a special tribometer able to simulate wide ranges of contact pressures and sliding velocities, the method is applied for a wide spectrum of work materials and lubrication conditions.

SŁOWA KLUCZOWE: cutting, friction, heat partition

ABSTRACT: Artykuł wprowadza nową metodę szybkiej identyfikacji modeli tarcia i partycji ciepła w skrawaniu.
