A 3D FEM model of Ti75 alloy tube spinning was established. The distribution regulation of stress
and strain during spinning process was analyzed. The influences of feeding, reduction and angle of roller on spinning process were obtained. The force and piling distance of spinning increased with increasing roller angle, feeding speed and reduction ratio. The PEEQ increased with increasing reduction ratio, decreased with increasing feeding speed.The PEEQ is hardly changed when feeding speed is above 1mm/ s. The PEEQ is almost constant when the roller angle are smaller than 20 degree. The PEEQ increased quickly with roller angle when the roller angle exceed 25 degree.
