Abstract：

It was studied the sheet metal drawing performance under three typical servo controlled slide motion modes: speed motion mode, oscillation motion mode and intermittent motion mode, and the influences of various motion modes on forming quality and forming limit were given. Compared with the uniform speed motion, the drawing limit heights of the specimens under the above three slide motion modes were all improved. Among them the intermittent motion mode performed the best with an increase of 10.9% of the drawing limit height, and the plasticity of the material could be further improved by the prolonged intermittent time and increased frequencies. Followed by the oscillation motion mode increased by 7.5%, as a result, the speed motion mode increased by 7.1%.
