Abstract：

In order to control the radial dimension error of parts in the multi-pass single point incremental forming, the influence laws of major forming process parameters on the radial dimensional error of parts were analyzed by response surface method, and the influence significance of each parameter and its interaction on the target were analyzed. Then, the fitness of experimental data was further evaluated, and the forecast model of radial dimensional error was proposed in the multi-pass single point incremental forming. Meanwhile, some optimal forming process parameters were obtained by the minimization algorithm and processing efficiency of such kind of process, and the precise control of radial dimension in the multi-pass single point incremental forming was realized. The results show that the influence of the secondary term for forming tool on the radial dimensional error is very significant, and the influences of reduction amount, feeding rate and interaction between forming tool and feeding rate are significant. In addition, four groups of superior process parameter combinations were obtained by the minimization algorithm. Thus, the combination of superior process parameters with the reduction amount of 0.32 mm, the tool diameter of Φ12 mm and the feeding rate of 1188 mm·min-1 are selected to improve the radial dimension error of parts in the multi-pass single point incremental forming.
