Effective Matching of Surface Roughness
Concerning the effective matching of surface roughness using a lathe, I have been asked to quantify Ra = C1* s^C2 v^C3 Re^C4, where Ra is surface roughness, s is feedrate, v is cutting velocity and Re is the nose radius of the tool.
I had performed an experiment to get the values of Ra for combinations of different v, s and Re. My problem is that I don't know how to use this data to define the constants in the relationship above. Can you tell me how to do this?
