But size effects like changed tribology [3] and material properties [4] usually result in smaller process windows for micro forming operations [5].
For deep drawing the size effect on the properties of material [4] as well as the size effect on tribology [7] are the most important ones [8].
The investigated material was pure aluminum foil with a thickness of 20 µm and a drawing ratio of 1.7.

Extensive in industrial uses, poplar wood is not only the materials for packing case, plywood, particle board, fiber board and rayon, but also is one of the major materials of paper [3].
As the largest importing country of original pulp and waste paper, the paper market risk of China is distinct, and seeking more papermaking materials is one of the means helping improve the irrational structure of papermaking materials of China.
Materials and methods Poplar I-69 of twelve-year-old with breast height diameter of 286 mm was collected from forestry farm of Anhui Agricultural University.
