Abstract: | This study investigated the influence of cutting parameters on the residual stress obtained in whirlwind milling of AISI 52100 steel. Single-factor and Box-Behnken experiments were separately carried out. A prediction model of residual stress was developed on the basis of response surface methodology using experimental data. Results indicated that the cutting depth was the dominant factor, and the interaction between cutting speed and tool number was significant. The developed model could be effectively used to predict surface residual stress within high confidence. The optimum value and cutting condition were validated by confirmation experiments. |
