Abstract
The coefficient of friction between a freshly cut titanium surface and a coated tungsten carbide pin is measured in-process with a cutting tribometer to emulate the tribological conditions between a titanium chip and the cutting tool. The sliding speed and the normal force are varied over the large range which is prevailing in conventional cutting. Large deviations from the Amonton friction model are observed and a new model is proposed. The complex influence of the velocity in lubricated contacts under medium loads is studied with respect to the coefficient of friction. The results are compared to results from pin-on-disk tests and spiral pin-on-disk tests.
