Abrasive cloth wheels with great flexibility can be used for complex surface polishing.In order to grasp the influence of the law of polishing process parameters on the TC4 surface roughness and improve the polishing quality,the process parameters influence law was analyzed through the single factor experiment.The surface roughness prediction model is established based on orthogonal test results and verified to be of significance.Process parameters coupling with the influence law of the surface roughness are analyzed with the process parameters optimized by the response surface method.Finally,blade polishing experiments show that the ideal polishing results can be achieved by the prediction model and optimized process parameters.
