A Surface Residual-Stress Model of Optimizing Milling Parameters for Milling Aluminum Alloy 6061

Article Preview

Abstract:

The residual stress is one important factor causing deformation and distortion. A mathematical model is presented. It predicts the surface residual-stress caused by end-milling. Response Surface Methodology (RSM) with the Takushi method is used to design experiment. The variance analysis (ANOVA) is conducted to determine the adequacy of the model. It is shown that the model offering good correlation between the experimental and predicted results, is useful in selecting suitable cutting parameters for milling aluminium alloy 6061.
