ANALYSIS OF THE PROCESSING SEQUENCE ON AIRFRAME STRUCTURES MACHING DEFORMATION
Keywords:Initial Residual Stress, Processing Strategy, Processing Deformation, Finite Element, Block Processing Sequence
In order to reveal the influence of different processing procedures on the machining deformation of the whole structure of aviation frame type, a prediction model for the deformation of frame type integral structure caused by initial residual stress was established based on finite element. According to the deformation law of frame parts caused by initial stress of blank, the deformation of whole structure parts based on aviation frame is minimized. The influence of processing process on deformation of frame structure is studied. The results show that when removing the frame material, the deformation of the workpiece can be slowed down by first removing the area with large deformation and relatively concentrated material. And symmetrical removal of the frame material can also slow the deformation of the workpiece.
