How 2D Finite element metal cutting simulation will help to find out surface rouness??

Hi all Metal cutting experts...



I have done done 2D finite element metal cutting simulation and validated with experimental force value. as we know.. from 2D FEM simulation, we can get only force data, stress-strain, temperature and somehow chip morphology. Can anyone kindly tell me how will this 2D simulation help me to link with surface roughness of the machined surface.



I will be  very gratefull to you all....

thanks in advance...
