| Abstract Scope |
Backward-cup extrusion has hard lubrication conditions such as high pressure, elevating temperature, and large surface expansion. This study focuses on the relationship between the surface expansions and forming conditions is experimentally measured. According to the main results, the minimum surface expansion ratio appears at the extrusion ratio of 3 to 4, and the punch nose without sharpness and roundness helps to inhibit the increase in the surface expansion. These evidences will be valuable to design the process conditions and the punch shape. |
