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.

For the sake of the axis accessory's figuration, the experiment of second wedge heavy section shrinkage was carried out.

Synchronous rolling with multi-wedge cross wedge rolling(MCWR) is an advanced technique in forming long axial parts, and it does not have disadvantages of the above two methods.
