Abstract: A
surface roughness model utilizing regression analysis method is
developed for predicting roughness of ultraprecision machined
surface with a single crystal diamond tool. The effects of the
main variables，such
as cutting speed，feed，and
depth of cut on surface roughness are also analyzed in diamond
turning aluminum alloy. In order to predict and control the
surface roughness before ultraprecision machining，constrained
variable metric method is used to select the optimum cutting
conditions during process planning. A lot of experimental
results show that the model can predict the surface roughness
effectively under a certain cutting conditions .
Key words: Surface
