Machining deformation prediction for frame components considering multifactor coupling effects
Z. T. Tang & T. Yu & L. Q. Xu & Zhanqiang. Liu

Abstract: The machining deformationprediction model was developed considering multifactor coupling effects includingoriginal residual stresses, clamping loads, milling mechanical loads, millingthermal loads, and machining-induced residual stresses. The machiningdeformation of a true frame monolithic component was predicted by this model.To validate the accuracy of prediction model, deformations also were measuredon a coordinate measuring machine. The deformations predicted by the model showa good agreement with the experiment’s results. The deformation prediction model can providean effective way to study further control strategies of machining deformationsfor monolithic component.
