Simulating machining in abaqus
Project Summary
This project researches into the use numerical
simulations of machining covering the studies from
the past and the current methods. Then a
specification is produced from the research to lay out
the values for a simulation in abaqus. The simulation
is then prototyped with a large mesh and is checked
for validity by comparison and improved. The results
are then used to produce a refined simulation and it
is evaluated.

Project Objectives
This project aims to research into and
simulate a cutting process using a
computational approach then validate the
results using experimental tests.
Then based on the research into the field and
the simulation results establish. Are modern
FEA simulations accurate enough to predict
real machining?
Project Conclusion
In conclusion the aim to research and
simulate a cutting process using a
computational approach was achieved
however it was not validated using
experimental tests this was because the
simulation proved to be far harder to get
working correctly than hoped.
