| Summary: | Understanding of the fundamentals of metal cutting processes through the
experimental studies has some limitations. Metal cutting modelling provides
an alternative way for better understanding of machining processes under
different cutting conditions. Using the capabilities of finite element models, it
has recently become possible to deal with complicated conditions in metal
cutting. Finite element modelling makes it possible to model several factors
that are present during the chip formation including friction at the chip tool
interface. The aim of improved understanding of metal cutting is to find ways
to have high quality machined surfaces, while minimizing machining time
and tooling cost. Friction behaviour at the chip-tool interface is one of the
complicated subjects in metal cutting that still needs a lot of work. Several
models have been presented in the past with different assumptions. In the
current model, the Coulomb friction model, which assumes a constant
friction coefficient, is used to model the friction in order to simplify the
model. The effect of the constant friction model is considered by analyzing
the result for several friction coefficient values and comparing them to the
previous work.As simulation tool for the purpose of this study, the FEM
software used is DEFORM 3D. DEFORM 3D is a robust simulation tool that
uses the FEM to model complex machining process in three dimensions. The
simulation results on cutting forces and thrust forces, and shear angle are
compared with experimental data in order to indicate the consistency and
acccuracy of the results when conducting the comparison. |
