Abstract

The redistribution of residual stress caused by material removal and the bending deformation during the processing of 7075 aluminium alloy sheet were studied in this paper. A continuous model for the redistribution law of residual stress in the plate during cutting is proposed and the influence of material removal rate on deflection and overall bending deformation of the plate is studied by theoretical analysis method. ABAQUS software is used to simulate the redistribution of initial residual stress and the overall bending deformation caused by material removal. The results of simulation and example are within the error range, which proves the reliability of the theory. The results show that there is a certain stripping depth in the stripping process, which can minimize the bending deformation in subsequent inventory. This conclusion has a certain guiding effect on controlling the residual stress of plate in actual production and the bending deformation in inventory process.
