The characters of flexible clamp stretch forming (FCSF) is introduced, the finite element model of FCSF is set up, and lots of numerical simulations for spherical part and saddle-shaped part are carried out. Contradistinctive analysis of strain, thickness and transitional length between RCSF and FCSF are investigated, and the minimum transitional length diagram of spherical part and saddle-shaped part are determined. FCSF machine was developed, and the forming experiment of spherical part was
more » ... ne. Consequently, the spherical part has good surface quality, which proves that the FCSF technology is feasible and the simulated results are valid.
