Abstract: A presently-preferred process for bending a workpiece comprises placing a first portion of the workpiece on a substantially flat surface so that a second portion of the workpiece overhangs an edge of the substantially flat surface, and securing the first portion of the workpiece on the substantially flat surface by clamping the workpiece between the substantially flat surface and a substantially v-shaped end portion of a male die. The presently-preferred process also comprises causing the second portion of the workpiece to pivot around a tip of the substantially v-shaped end portion by rotating a bending die around the tip while the bending die contacts the second portion of the workpiece.
