The selected parameters of this experiment are the control contact length, the second rake angle, the tool nose radius, the width of chip breaker groove and the radius of chip breaker groove. The experiment design matrix of five parameters is disposed by Response Surface Methodology (R.S.M.). The prediction model of tool geometry on chip radius is established from the SAS regression. Then the significant parameters of tool geometry parameters on chip radius and the reliability of the prediction model are investigated by SAS software. The width of chip breaker groove and the radius of chip breaker groove affect obviously the chip radius shown in the analysis. The adequacy of this prediction model is also examined by F-ratio test and trial sets. Therefore the best design of tool geometry is obtained by this prediction model.
