Machining deformation prediction for frame components considering multifactor coupling effects

摘要

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.
