| Abstract: |
| In order to study the influence of each polishing parameter on surface roughness in high frequency short pulses electrochemical polishing of aluminum alloy, polishing parameters such as pulse width, polishing voltage, polishing clearance and etc. were designed by orthogonal experiment scheme. Firstly, the effect of each parameter on surface roughness was analyzed by the difference method qualitatively, and then mathematical model of polishing was obtained by the method of stepwise regression, finally, regressive equation of quartic function ( optimum regressive equation) is confirmed to be the mathematical model that had been proved by single factor test. Thus the influence of each polishing parameter on surface roughness can be studied quantificationally, which can be used for reference for investigation and application of electrochemical polishing of aluminum alloy. |
