Abstract

The machining deformation prediction model was developed considering multifactor coupling effects including original residual stresses, clamping loads, milling mechanical loads, milling thermal loads, and machining-induced residual stresses. The machining deformation of a true frame monolithic component was predicted by this model. To validate the accuracy of prediction model, deformations also were measured on a coordinate measuring machine. The deformations predicted by the model show a good agreement with the experiment’s results. The deformation prediction model can provide an effective way to study further control strategies of machining deformations for monolithic component.
