Abstract: Regarding the sizing surface zone as a quasi-plasticity one and using yielding criterion, a new drawing force calculating formula in which the sizing surface friction was taken into account is deducted. The calculated and experimental results show that for rod drawing and tube sinking, it is permissible to neglect the effect of the friction at the sizing surface, but for tube drawing with a stationary mandrel, especially for thin-wall tube drawing this friction should not be neglected.
