VTube Overbend Calculations for Springback
VTube-STEP and VTube-LASER Overbend Calculations
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. |
