A young engineer designs a beautiful 3D model of a piercing punch in SolidWorks. He sends the DXF to a wire EDM. The punch looks perfect, but on the press, it breaks on stroke 50. Ostergaard’s answer: The engineer forgot the "land" length. Ostergaard teaches that punches need a reduced diameter back section to prevent buckling. The CAD doesn't teach that; the old book does.
