Two-Axle Bending Technique with Elastic Roller (TABTER) is a kind of advanced manufacturing method for bending tubular parts, specially suiting for the difficult-to-work metal materials with high specific strength, and it can obtain a finer forming accuracy. Now the technique has been applied to bend split-sleeve and missile body cylinder successfully. In existed theories, the forming precision of the parts is controlled by adjusting the feed distance between the two axles. But because of the aging problem of the elastic roller and other uncertain factors, the feed force may be different even using the same feed, thus the forming precision cannot be ensured. To solve this problem, the forming theory by controlling the feed force between the two axles is proposed. Then the NC model of forming the non-circular cross-section tubular parts based on the theory is built. At last, the NC prototype machine is developed and some experiments are carried out on the machine.
