Paper Title:
The Study on Suppression of Dimples in Digital Multi-Point Stretching Process
  Abstract

In this paper, the basic theory of multi-point stretching process was introduced, the process of multi-point stretching of saddle part was simulated, the generation and suppression of dimples were studied [1~3]. The results showed that dimple is specific defect in the multi-point stretching process; the dimples can be suppressed effectively by elastic cushion technology. Thicker elastic cushion is more effective to suppress dimples, but the error between formed workpiece and objective shape will get large. By adopting elastic cushion with appropriate thickness, workpiece with smooth surface can be obtained and the forming error is small.
