Research on Overall Aluminum Alloy Flange Machining Deformation

Machining deformation has been a bottle-neck issue in aeronautical manufacturing field. Due to the large amount of material removal and other issues, machining deformation is predicted more difficultly during the process of 2026-T3511 aluminum alloy rim. Hence a simple full-size model of margin monolithic was built to study the deformation under the influence of residual stress releasing. The process of the structural parts was simulated and the deformation law of overall structure considering residual stress releasing only was revealed. Through the comparative study of different machining processing, control strategy reducing the final part machining deformation and optimum machining allowance range were proposed.
