Abstract: With upper bound method and least energy principle,the conditions are established of drawing and breaking workpiece with cross wedge rolling technique to form axial symmetry spare parts.The figure of working limits is obtained about forming axial symmetry spare parts with cross wedge rolling technique by combining study results in this article with the ones in documents [1~3].

Key words: cross wedge rolling technique, ladder axis, forming, the figure of working limits
