　　Fifth, turn the hole: the hole along the surrounding material translated into its side flange of a stamping process.
　　Sixth, blanking: material separation along the closed contour of a stamping process, being separated material into the workpiece or process parts, most of planarity.
　　Seventh, plastic: relying on material flow, a small amount of change in step shape and size, in order to ensure the accuracy of the workpiece a stamping process.
