Eliminating final trim shearing of hydroformed tubeThe most common way to establish tube length after hydroforming is by cutting or shearing the tube to a specified dimension; however, cutting out this step can reduce scrap. A new method designed to eliminate this step combines forming the end of a tube to resemble its final form with using a hydroform die to correct end position variations off the bender. While this approach eliminates the final shear trim operation, it also presents new challenges.

Adaptive bending: Achieving accurate first-piece bending resultsAdaptive 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.
