A Study on Surface Roughness Prediction Model Based on Response Surface Methodology

Based on analyzing the shortcomings of the past methods of building a surface roughness prediction model,response surface methodology(RSM) was adopted to build a prediction model of surface roughness for milling steel and steel alloy.Through the verification of the built prediction model of surface roughness,result shows that the prediction accuracy and generalization of the model are very high and the model can conveniently predict the effects of milling parameters on surface roughness of machined surface,which contributes to accurately understand the variation law of quality of machined surface following milling parameters and provides the foundation for properly selecting cutting parameters and controlling surface quality.
