Adaptive bending allows press brake operators to measure a bend angle during the forming process and feed the information to the numerical control. The article discusses springback and how to determine it and the fact that when air bending, 90 percent of problems result during initial setup, and only 10 percent result from springback. It also discusses using an angle control system, methods of measuring angles, and requirements for angle measurement systems.
