Abstract：

The low precision is a critical factor that obstacles the development of single point incremental forming. For the difficulty of high temperature reprocessing in the single point incremental forming, a single increamental forming method by liquid medium heating was proposed, and the suitable single point incremental forming temperature of magnesium alloy sheet AZ31B was explored by increasing temperature gradually. At the same time, the influence of forming angle on the accuracy was studied for processing pyramidal parts of magnesium alloy AZ31B by the single point incremental forming at this temperature. The results show that this method of liquid medium heating is feasible and can complete the single point incremental forming process for the magnesium alloy sheet at the heating oil temperature of 200 ℃. Furthermore, the influences on the accuracy are from two forms as wall bulge and edge springback, and the wall bulge and edge springback are reduced with the increasing of forming angle.
