... geometries with respect to die length and taper. The figure on the right in Fig. 1.12 shows the shear angles on the die (instead of having the shear angle on the punch) to achieve lower forces. This would enable the part to be flat instead of bent, which occurs when the shear angle is on the punch...

... decreasing in magnitude toward the neutral axis. The setup and tooling for press-brake forming are relatively simple ( Fig. 19 ). The distance the punch enters the die determines the bend angle and is controlled by the shut height of the machine. The span width of the die, or the width of the die opening...
