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

Three Step Process for Predicting Springback

  • 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: Formula constant values are calculated and used in a springback formula to predict overbend to overcome springback at any angle.




VTube-STEP and VTube-LASER

The Overbend Calculator is also embedded in VTube-STEP and VTube-LASER because the fixed and proportional springback values are included in the Part Setup menu - and have an effect on sending especially new data to the bender.

To access the calculator inside VTube, follow these steps:

STEP 1: Right click anywhere in the white column in the Part Setup menu.

STEP 2: Choose "Show Overbend Calculator" in the context menu (the popup menu).

STEP 3: Make a part with two test bends. Typically they are 20 and 120 degrees. The bender is set to bend these angles and a test tube is bent.

STEP 4: The actual resulting bend angles are measured and entered into the overbend calculator.

STEP 5: Formula constant values are calculated and used in a springback formula to predict overbend to overcome springback at any angle.

STEP 6: Press the "Save to Part Setup" button. The values will now be displayed at the bottom of the Part Setup menu.

These two calculated values will be used to calculate overbend to overcome springback when sending data to the bender. This image shows a button inside the Bender Setup menu in VTube-LASER.
