The importance of machining process in todays
industry requires the establishment of more practical approaches to
clearly represent the intimate and severe contact on the toolchipworkpiece
interfaces. Mathematical models are developed using the
measured force signals to relate each of the toolchip friction
components on the rake face to the operating cutting parameters in
rough turning operation using multilayers coated carbide inserts.
Nonlinear modeling proved to have high capability to detect the
nonlinear functional variability embedded in the experimental data.
While feedrate is found to be the most influential parameter on the
friction coefficient and its related force components, both cutting
speed and depth of cut are found to have slight influence. Greater
deformed chip thickness is found to lower the value of friction
coefficient as the sliding length on the toolchip interface is reduced.
