Study on the Deformations Caused by the Original Residual Stresses of Aluminum Alloy

Abstract:

The machining deformations caused by the release and redistribution of original residual stresses were studied by the theoretical analysis and finite element method. The research results show that the release and redistribution of original residual stresses result in machining distortion of the plate part. There exists an optimal value of material removal amount according to original residual stresses. When the amount of the material removed exceeds the optimal value, the machining deformation can be controlled effectively.
