Dynamic springback compensation method in incremental forming machining process

The invention discloses a dynamic springback compensation method in an incremental forming process, which comprises the following steps of: determining the springback angle of a part according to the type of an original plate, the thickness of the plate, the forming angle and the forming depth of a machined workpiece, the radius of a tool head, the x-axis feed rate, the z-axis feed rate and the like, and calculating the theoretical contact range of the tool head and the plate and the index of a node to be machined; nodes can be taken from the plate according to the feeding amount of the tool head, and the theoretical minimum distance between the plate and the tool head is judged according to the nodes, so that the number of the nodes during springback collision can be calculated. In other words, if springback collision occurs in the machining process, the node closest to the tool head becomes a first collision point, so that the forming quality of the part can be guaranteed only by controlling the tool head t
