Greetings Melesse,

I would recommend you to first define your priority and outcomes (forces, temperatures, chip thickness...) then completely establish your input conditions. This paper gives a general introduction to machining simulations:

*"Recent advances in modeling of metal machining processes". DOI: 10.1016/j.cirp.2013.05.006.

Then you could start following an example in ABAQUS to replicate results like:

"Prediction of micro-milling forces with finite element method". DOI: 10.1016/j.jmatprotec.2011.05.020.
