2. Sheet thickness is thinned, surface area is increased in the NC incremental sheet metal parts forming process , and sheet forming point by point is to lead to the whole sheet deformation. 认为，板料零件数控渐进成形是使板料的厚度减薄，表面积增大，靠逐次的变形累积产生整体的变形。
3. The change rule of peak flow stress: extrusion sheet>hot rolled sheet>cold rolled sheet. 峰值流变应力变化规律：挤压板＞热轧板＞冷轧板。
