Abstract

A forming process for producing sharp corners in sheet metal workpieces, and a press brake useful in carrying out such a process, involving a male forming die (100) incorporating a nipple (160) for extruding the sheet metal stock (320) material into the adjacent region (240, 280) defined by the female coining die (120) for forming a sharp corner in the workpiece.
