XYZ Intersection Tolerances

• Back to VTube-LASER

You can 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".

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

The more positive the value the more elongation is removed from the cut length. A typical value is between 3 and 5 (percent).

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.

(You can click on the image to see it larger.)

The intersection deviation grids allow you to set the default tolerance to every value in a row, column, or even the entire grid using a popup menu

To use this feature, single click on a tolerance value, then right click and choose the action in the popup menu.

The screen images on the right show an example of before and after changes made to an entire column:

The XYZ Intersection deviation values can be included in reports:

1. plus tolerance values
   
2. minus tolerance values
   
3. out of tolerance values
   

The first Inspection Report in the reports menu is good for showing this data.
