VTube-LASER - End Scan Diameter Qualification Tolerance

End Scan Diameter Qualification Tolerance Back to VTube-LASER

How the Tolerance Works

The End Scan tolerance allows VTube-LASER to control which points are accepted as potential end-scan points based on how far the points are from the A-End and B-End Diameter values. The image above illustrates a tolerance of 10 millimeters. Any end scan points within that region will be qualified. See the orange points in image. The red points are outside the tolerance, so they are rejected. The tolerance is measured from the out diameter in both directions - both positive (away from the centerline) and negative (toward the centerline).

How to Set the Tolerance

You can set the tolerance in two places in VTube. One place is in the System Options / Measure 2 menu.

The second place to edit the value is in the VTube-LASER Measure Setup menu's "Other" tab menu.

Choosing Values

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

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.
