For some applications, it is important for fabricators to calculate the cut length of parts in advance of bending. The tube elongation percentage value lets you remove elongation from the cut length before bending begins. For example, you may want to quote a project with tens of thousands of pieces - and you want to make a better calculated estimate of total material use.<br><br>

===Reason 1: For Reuse on New Parts===
 
−
You could setup and bend the part and measure the cut length before and the length of elongation on the end of the tube after bending for every part. Or you could store this information in VTube's springback compensation library and use it to predict the lengths of future parts with similar materials and setups. (VTube stores the tube elongation % for a setup inside the springback table.)

===Reason 2: To Unbend Parts with Components in VTube===
 
−
VTube can unbend tubes in real-time. Unbent parts with holes and components unbent are more useful if they take into account proper tube elongation. For example, you may need to unbend a tube with holes in order to drill the holes before bending. Accounting for elongation becomes critical in this situation.

The Tube Elongation Percentage Calculation Method

VTube-LASER can calculate Tube Elongation Percentage by subtracting the current CUT LENGTH from the MEASURED LENGTH - then calculate the percentage by comparing that change to the total ARC LENGTHS in the measured tube.

The formula used is (Measured Length - Cut Length) / (Arc Length Sum for Whole Tube) X 100




How to Calculate a Single Tube Elongation Percentage in VTube-LASER

Follow these simple steps to calculate tube elongation:

  1. Design a simple part with a 90-degree bend in the VTube-LASER MASTER data. Use whatever radius is on your bender.
  2. Calculate the cut length in the Part Setup using the popup menu.
  3. Cut a straight section of tube to that cut length.
  4. Bend the part in the bender.
  5. Measure the part.
  6. Use the popup menu in the Part Setup menu to recalculate the tube elongation percentage.

Note that it is critical that you have entered the ACTUAL CUT LENGTH of the part you just bent for VTube to properly calculate the tube elongation percentage value.


VTube Can Also Use Multi-Elongation

For applications that mix bending radii and bending types, multi-elongation lets you set the elongation % uniquely for every bend. See Multi-Elongation in VTube for more information about using multi-elongation.
