Abstract：

The process of hole\|cup drawing is studied by coordinate\|grid method in the paper.The strain distribution from the experiment indicates that there are deformation tendencies of drawing and flanging in the hole\|cup drawing process.The tendency is related to,in the same die prameter and technology condition,the size of hole.And the tendency changes slightly when the die parameter changes.The studying result in this paper provides the theoretic basis for the deformation tendency analysis and the deformation control of hole\|cup drawing process.
