XYZ Intersection Tolerances

• Back to VTube-LASER

The XYZ intersection tolerances are designed to allow you to qualify a part using +/- tolerances to the intersection.

The intersection tolerances are based on values are that follow the three axes in a coordinate system. Since the tolerances measure along the axes, as of version 1.93, these tolerances can be positive or negative to also indicate a direction.

You can set these tolerances in two places in VTube-LASER. The first place is in the Inspection Data menu.

Click on the Change Grid Setup button until you see the tolerances in the grid like we show in the image on the right.

Then select and change any tolerance value. The grid will allow you to edit only the tolerances.

The second place to edit the value is in the VTube-LASER Expanded Window.

Click on the Expanded Window button to display the Expanded Window, and then make changes to the tolerances there.

The benefit of the Expanded Window is that you can view all the tolerances at the same time.

• A tight qualification is 1 millimeter. It is much more challenging to measure the end scan with a tight tolerance. Keep in mind that tube deformation will make tight tolerance end scans more challenging.
  
  

• A much easier / quicker qualification is to increase the value to much high number - like 25 millimeters. (Many customers use 25 millimeters to avoid this qualification from occuring completely - and making end scans much easier.)
  
  

Set the default value by clearing the VTube project, then changing the value, then saving the setup to the default file in the System Options - Project Setup menu.
