For the key issue of disordered secondary deformation caused by mismatched residual stress distribution in thin-walled aerospace parts, the typical thin-walled aerospace special-shaped parts were selected and a deformation suppression method based on the residual stress energy field model and the evaluation index of feature matching degree was proposed. By using milling simulation to extract residual stresses of each parameter, the residual stresses were redistributed, and match through the residual stresses of each feature were matched. It was found that there will be coupling superposition and cancellation characteristics between adjacent and opposite features. Under the action of a single residual stress field, the maximum deformation of the workpiece was significant. After using the multi-residual stress field co-matching under high feature matching degree, the maximum deformation was reduced by nearly 28.6%. Experimental data show that the optimized processing parameter system can achieve dynamic balance between features, the actual deformation of the special-shaped parts is reduced by the maximum 27.2%, and the roundness is reduced by the maximum 49.5%, which verifies the effectiveness of this method. The research confirms that the stress distribution optimization strategy based on the coordinated regulation of residual stress energy field and feature matching degree has significant engineering value for the overall deformation control of aerospace thin-walled parts.
