Abstract：

For the variable angle truncated cone, based on the incremental forming mechanism and chosen equivalent stress and sections springback value of forming part as major research objects, the influences of different process parameters on the springback of single point warm incremental forming were studied by software ANSYS/LS-DYNA. Furthermore, the influence regulations of forming temperature, friction conditions and tool diameter on the springback of single point warm incremental forming for magnesium alloy AZ31B were researched mainly. The results show that the springback can be effectively controlled when the forming temperature is 250 ℃, the static friction coefficient is 0.2, the coefficient of kinetic frictionis is 0.1 and the diameter of the tool is Ф10-Ф12 mm.
