Abstract：

The influences of process parameters on the formability of magnesium alloy AZ31 in rotational incremental sheet forming were studied by orthogonal test. The variable-angle cone cup model was adopted and the forming rupture angle was regarded as the test indicator. The results show that the order of single factors affecting incremental formability of magnesium alloy AZ31 performance from the primary to the secondary is, spindle speed, Z-axis feed, tool head diameter, feed velocity and tool material, in which spindle speed is the most important factor. On the premise of good formability and surface quality of the sheet metal, a faster feed rate，larger Z-axis feed rate and tool head diameter should be chosen in order to save time. Tool materials have little effect on the formability, which can be ignored. The optimum process parameters in the orthogonal test are tool speed 4500 r·min-1, feed rate 300 mm·min-1, Z-axis feed rate 0.3 mm, the tool head diameter Φ12 mm, tools material HSS4341 and forming rupture angle 88.25°.
