Investigation on Stretch Forming Process of Thick Double-Curved Aluminium Alloy component

Abstract

Stretch forming process is extensively employed to manufacture aluminium alloys aircraft panel part which possesses large size. These panels usually have a various double curvatures geometric contour. A stretch forming process is proposed to make this part. It indicates that this process which is optimized by research work can be used to manufacture the thick aluminium panel possessing double curved contour with high accuracy. Furtherly in help of the optimization of process parameters by this research work, the manufacturing process may be simplified by means of reducing the forming steps. This stretch forming process has been applied in industry manufacturing. This method is feasible for further stretch process design.
