This is software that calculates overbend necessary to overcome springback in bends.


Three Step Process

  • STEP 1: Two test bends are made. Typically they are 20 and 120 degrees. The bender is set to bend these angles and a test tube is bent.
  • STEP 2: The actual resulting bend angles are measured and entered into the overbend calculator.
  • STEP 3: Two values called "proportional" and "fixed" are calculated and used in a springback formula to predict overbend to overcome springback at any angle.
