How To Calculate Cut Lengths in VTube

Import tube data from solid models, then produce reports, and send data to benders.

Calculating Cut Length in the Part Setup Menu

The Cut Length value is a value that can be entered manually or calculated automatically. Calculate the cut length of the tube in the Part Setup menu in either STEP or LASER modes.

To calculate the cut length, right click on the Part Setup menu, and choose "Calculate Cut Length".

How to Calculate and Remove Elongation From the Cut Length

VTube also uses the Tube Elongation Percentage value to remove anticipated elongation.

A typical value is between 3 and 5 (percent).

The more positive the value the more elongation is removed from the cut length. For example, "4" removes 4% from all the arc lengths when calculating the cut length of the tube.

See images on the right for an example of changes to the Cut Length before and after calculation when removing 4% from the arc lengths.

Recalculate the Cut Length after the change to the tube elongation percentage for the new value to take effect in the Cut Length calculation.
