Abstract：

For the complex deformation and numerous influenctial factors in plate multi-point incremental forming process, the selection of different parameters has a great influence on the quality and efficiency of the forming process. The finite element model of multi-point incremental forming process for pyramidal cone was established by MSC.MARC software, and then the test scheme was designed accordingly. The influences of different parameters on equivalent strain were studied and their distributions were analyzed. The results show that the equivalent strain increases with the increasing amount of feed and becomes more significant when the point is closer to the tool. Although the equivalent strain increases with the increasing speed of feed, the influences will decrease significantly when the feed speed increases to a certain extend, and the forming angle has little influence on the equivalent strain.
