Multi-roll stretch forming process is a new flexible manufacturing technique that the general idea of discretizing is put in use in the design of stretch forming machine. In the new process, the metal sheet can be more easily formed, and the flexibility can be much higher, which the traditional process cannot compare with. In this paper, in through extensive numerical simulations of the MRSF stretching process of toroidal saddle parts, A series of finite element simulations have done for the process of forming toroidal saddle parts using different lubricant and two kinds of rollers named damped rollers and ordinary rollers. The results show that the smaller the friction coefficient is, the easier the center of toroidal saddle part is stretched. Damped rollers can increase the stretching force and the ordinary rollers can increase the mobility of sheet metal. Arranging the damped rollers and ordinary rollers at a reasonable position can make the workpiece a more uniform stretching.
