| Abstract: | On the basis of full consideration of the slip band appearing and the shape fixability of forming parts,reasonable conditions in stretch forming of airplane mirror skins have been determined by means of analysis of the effects of stretching velocity, geometrical dimensions of blank, geometrical parameters of dies and lubrication methods on forming quality. The results show that improving the deformation uniformity of sheet materials, delaying the appearance of slip band, and increasing the material deformation degree of the forming region are the main measures of working out the optimum process parameters and improving the forming quality of mirror skins. |
| Keywords: | skins stretching aluminum alloy slip band spring back |
