Abstract：

Focused on the problems of lower forming efficiency and the workpiece tends to instability due to the non-homogenous force in the shaped surface during incremental forming and larger forming force，and based on the merits of single point incremental forming and multi-point forming process, the multi-point incremental forming was presented. The corresponding forming control system was developed according to the principle of forming and path planning. Using DMC2610 controller as core and the master-slave control mode of “PC and controller”, the software of system was designed by VB6.0. The hardware and the software structure of the control system and the implementation method were introduced in detail. The result shows that the control system has good flexibility and openness，which meets the needs of experimental study for the current multi-point incremental forming.
