Multi-point stretch forming (MPSF) technology is a flexible forming method, and it eliminates the need to the traditional fixed shaped-stretching die and, therefore, is a suitable method for forming small batch quantities of aircraft outer skin parts. Multi-point stretch die (MPSD) is composed of a punch element matrix, the size of punch elements and the radius of the hemispherical end of elements are the two important geometrical parameters of MPSD and they are major factors to influence the shape accuracy of MPSF parts. The smaller size of punch elements makes the punch element number of MPSD larger in the same area. MPSDs with different element numbers and different hemispherical end radii are used for stretch spherical and toroidal saddle-shaped parts. The dimples and the shape error of MPSF parts were analyzed, and the results show the influences of punch element number and element hemispherical end radius on forming results. MPSF tests show that the forming effect of MPSF is excellent.
