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

Any time VTube-LASER has these three conditions it can calculate tube elongation percentage:

  1. MASTER XYZ centerline data is present

  2. MEASURED XYZ centerline data is present (You have measured the tube.)

  3. You have entered the pre-bent Cut Length value in Part setup of the part that you just measured

If these three conditions are true then you can right click on the Part Setup menu, and use the recalculate tube elongation percentage value.

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.
