As lubricant oils that give the environment pollution are used in usual press forming process, a new processing technique without oils is desired. The efficiency of deep drawing process is restricted by the wrinkles and breaks in the blank which take place in the process. As the process limit is improved by reducing the friction between the blank surface and the punch. In this study, experiments are conducted by using polymer films as a lubricant. The effect on the punch load is also investigated. FEM analyses are conducted to obtain the effect of friction quantitatively.
