Abstract: Lead screw high-speed cold roll-beating is a new single-point incremental forming technology which is die-free and unconstrained. The principle of the forming process is analyzed. Modeling, meshing and parameter selecting for forming process simulation with ABAQUS are discussed. The lead screw cold roll-beating forming process simulation is carried out; stress & strain changes and metal flowing law are analyzed. Experiments are carried out with the self-developed experimental equipment. The experimental results are consistent with the simulation results, thus the validity of the simulation and feasibility of the forming process are verified.
