The evolution of precision bending: Bending moves further from art, closer to scienceThree decades ago bottoming with penetration, or coining, was the only way to achieve high accuracies on press brakes, and this meant fabricators endured high tooling costs. Over the years precision air bending with CNC hydraulic press brakes using precision-ground tooling evolved to become the dominant forming method in the precision market. However, it took some significant machinery advances to get there.
