VTube Overbend Calculations for Springback

Embedded Overbend Calculator

The Overbend Calculator is 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 the final bend angles when sending new data to the bender, and when making corrections to the bender.

Steps to Calculate Overbend

<td width=400>

To access the calculator inside VTube, follow these steps:

STEP 1: Right click anywhere in the white column in the Part Setup menu. </td> <td> </td> </tr>

<tr> <td width=400> STEP 2: Choose "Show Overbend Calculator" in the context menu (the popup menu). </td> <td> </td> </tr>

<tr> <td width=400> 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. </td> <td> </td> </tr>

<tr> <td width=400> STEP 4: The actual resulting bend angles are measured and entered into the overbend calculator. </td> <td> </td> </tr>

<tr> <td width=400> STEP 5: Formula constant values are calculated and used in a springback formula to predict overbend to overcome springback at any angle. </td> <td> </td> </tr>

<tr> <td width=400> STEP 6: Press the "Save to Part Setup" button. The values will now be displayed at the bottom of the Part Setup menu. </td> <td> </td> </tr>

<tr> <td width=400> 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. </td> <td> </td> </tr> </table>
