The formability of aluminum sheet(Al 1100), i.e., the maximum effective cup height, the uniformity of drawn cup height, the limiting drawing ratio, the thickness distribution of drawn cup and the maximum drawing load are discussed for the arbitrary quadrilateral cup drawing. Two blank shapes are adopted to compare the above formabilities. One(h-bl) is designed by the slipline theory and the other( G-bl) is the conventional shape. The five punch shape factors are considered to investigate the wide range of formability. As a result, the theoretical blank shape(h-bl)is recommended to accomplish the higher effective cup height, the larger limiting drawing ratio, the superior uniformity of drawn cup height and more smooth thickness distribution.

The formability of aluminium sheet(Al 1100), i.e., the maximum effective cup height, the uniformity of drawn cup height, the limiting drawing ratio, the thickness distribution of drawn cup and the maximum drawing load are discussed for the square and rectangular cup drawing. Two blank shapes are adopted to compare the above formabilities. One(h-bl) is designed be the slip -line theory and the other(G-bl) is the conventional shape. The five punch shape factors are considered to investigate the wide range of formability. As a result, the theoretical blank shape(h-bl) is recommended to accomplish the higher effective cup height, the larger limiting drawing ratio, the superior uniformity of drawn cup height and more smooth thickness distribution.
