Surface Roughness as a Function of Work Done by Tangential Force in Magneto-Rheological Finishing

Abstract:

This paper shows the derivation of a proposed process equation for surface roughness change during magneto-rheological finishing (MRF), where surface roughness is expressed as a function of work done by the tangential force. By expressing surface roughness as a function of the work done, the equation enables real-time prediction of surface roughness change during an MRF process from the input of real-time force data. Experiments were carried out to verify the validity of the proposed equation for different tool revolution speed and different tool-to-surface gap. It was found that there is a strong correlation between surface roughness and work done for the said variation of experimental conditions. The theoretical roughness curves generated from the proposed process equation also fit the experimental data reasonably well.
