Check.jpgNEW - LRA POPUP MENU COMMAND SPLITS ONE BEND INTO TWO FOR MORE ACCURATE MEASURING QUALIFICATION and BENDER CORRECTION

Splitting a bend into two adjacent half-bends manually is a bit complex. So we added this command to make it easy.

This new "split a bend" command is useful for when a very high bend angle throws its intersection point far from the tube and then creates unreliably high swings in the tangent deviation and bender correction data.

After splitting a bend into two adjacent half-bends, you can use the SPLIT BEND measuring feature to scan the inside and outside of the actual bend to overcome this problem.

This new command is available in these grids:

  • Incremental LRA
  • Springback Compensated LRA
  • Absolute LRA

Follow these steps to setup VTube-LASER to split a bend then turn on "Split Bend Measuring"

1 - Select the bend to split in an LRA grid.

2 - Right click.

3 - Choose "Split Selected Bend into Two Bends"

4 - In the Bend Setup tab above the XYZ data, click on Split Bend Setup.

5 - In the Split Bend Setup window, set the STRAIGHT with the ZERO straight length to "Split Bend at Apex" (It will equal the BEND number + 1). Watch the data compress and highlight in the LRA grid when you exit the window.


VTube-LASER will now be ready to measure with the Split Bend scanning feature.

See VTube-LASER Split Bend Feature for details on the Split Bend measuring feature.
