The end milling of nickel-aluminum alloy has been widely applied to the manufacture of seawater applications, while the prediction of residual stress induced by this process is seldom reported. An analytical model of residual stress is proposed, based on mechanical loading and thermal loading during end milling. For the first time, the sequential discontinuous variable mechanical loading feature of end milling is taken into consideration. Also, the analytical model of stress field in the workpiece during cutting is analyzed which is intermediate variable to study residual stress. Model predictions are compared with experimental data and FEM method for cutting forces, cutting temperature, and residual stress.
