Machining deformation has been a bottle-neck issue in aeronautical manufacturing field. Based on finite element simulation, the influence of original residual stresses on the deformation in the process of machining for aeronautical monolithic component was studied. The redistribution law of residual stresses during machining and the trend of deformation change were analyzed. The simulation conclusions agree with experimental results. The machining deformation characteristics due to residual stresses were analyzed and the simulation of different machining path was carried out. The results indicate that the research on deformation caused by residual stresses alone can neglect the effect of machining path. The coupling effect between residual stress and milling force was taken into account and the simulation was performed for different machining path.
