| Abstract Scope |
High-speed shearing was studied to potentially improve sheared-edge quality for steel. The AIRAM pneumatic press can provide significantly higher speed than a conventional press at low energy cost. The maximum speed can reach over 1.5 meters per second depending on equipment setup. The study evaluated the pneumatic press that could increase the slide speed up to 1.5 meters per second. Various grades of steel, BH340, DP780 and Gen-3 980, were sheared using the pneumatic press with two different pressure levels as well as using a conventional press with 0.2 meters per second with the same tooling. The edge quality of the sheared blanks was evaluated using half specimen dome test (HSDT) and micro-hardness. The effects of the high-speed shearing are discussed in this paper. |
