Abstract：

In order to study the influences of each process parameter on the forming performance of single-point incremental forming with die of straight-wall cylindrical parts, four parameters about layer spacing, tool head radius, feed rate and forming passes were optimized and designed by orthogonal test respectively. Then, the thickness of sheet deformation zone was simulated, and the influences of each process parameter on the minimum thickness of sheet after forming were obtained by range analysis. The research indicates that in the process parameters of sheet metal forming, the largest influence on the minimum thickness is forming passes, while tool head radius is the smallest. After optimizing the aluminum alloy 1060 plate with 1 mm thickness,the optimized thickness of sheet is 0.389 mm, which is 60% higher than the minimum thickness of 0.242 mm after two passes. Therefore, in the incremental forming process of strainght-wall cylindrical parts,the number of forming passes can be appropriately increased under conditions permitted by forming time to improve the forming qullity.
