Abstract：

By using the NC incremental forming machine and breaking the way of traditional warm incremental forming by external heat sources，AZ31B magnesium alloy sheets were formed with green friction heat created by the sheet and rotating tool. By comparing the effects of different lubricants on the formability and formed surface roughness of AZ31B magnesium alloy sheet, the results show that the magnesium alloy sheet has a better incremental formability with high temperature lithium base grease than with graphite powder, MoS2 powder, graphite spray and adhesive type graphite, and its forming angle is equal or greater than 60°,meanwhile the formed surface roughness Ra value is about 2.47μm.
