Abstract

In aerospace equipment manufacturing, the machining deformation of the large integral structure is seriously influence on the machining efficiency and the accuracy of the parts. Based on the theory of elastic-plastic theory, the finite element analysis model of machining deformation of 3D integral frame is established, and the removal process of the material is simulated by using the technology of element birth and death. The deformation law of the initial residual stress release caused by the initial residual stress is studied, and the cutting experiment is designed, and the deformation of each milling is measured by using a three-dimensional coordinate measuring machine. Through the comparative analysis of the simulation data and the experimental data, it can make a conclusion that establishment of a correct analysis of the model can predict the machining deformation, and reduce the machining deformation.
