In this study, the experimental considerations of the friction factors are presented in a few cases. The friction factors in the cases of, first, the drawing quality material, SPC3C through the non-coated die of base material. GC30, secondly, SPCC through the Cr-coated GC30 die, and lastly. SPCC through the TD heat treated STD11 die, are measured experimentally both for the increasing die temperature and the blank holding forces. The results show no considerable variations of the value of friction coefficients according to the change of both the die temperature and the die treating conditions.
