Abstract：

In the single point incremental forming, the forming limit is usually represented by the maximum forming angle, and the study on the forming limit can be used as a reference for the experimental research of the material in the late stage for the hot incremental forming. A method of heating magnesium alloy AZ31B sheet by oil bath was proposed, and the hot incremental forming experiment was carried out. Then, the suitable processing temperature was explored by increasing the temperature gradient, and the forming limits of different sheet thicknesses at the suitable processing temperature were obtained. The results show that the incremental forming experiment with good results can be finished under about 200 ℃ in the oil medium. Finally, the forming limit of 1.5 mm thickness sheet is 60°-62°, but 45°-47° for that of 1 mm thickness sheet at the suitable temperature.
