Finite Element Simulation and Analysis of Part Deformation Induced During Milling of Thin-walled Aerospace Monolithic Structure Parts
During high speed milling of thin-walled monolithic structure parts, the geometrical and dimensional variability is governed mainly from the choice of process parameters such as operation sequence, selected cutting tool path strategies and the cutting parameters. Therefore, it is necessary to judge the validity of a given process plan before going into actual machining. In this paper, a finite element analysis (FEA) based milling process simulation system was developed to predict machining deformation of aerospace thin-walled monolithic structures. Some key factors such as initial residual stress, cutting loads, cutting sequence and tool path were introduced synthetically into the simulation system. The prediction accuracy of the simulation system was validated experimentally and the obtained numerical and experimental results were found in good agreement.
