REPEATABLE END SCANS

Repeatability issues on the ends is the most common problem in GR&R tests. Fortunately it is also the easiest to fix. It involves training users to perform a visual check of the model in the viewport after VTube calculates the end points.

Use Visual Feedback

In VTube-LASER, operators can use visual feedback to ensure that end point projections are good. This is an example of the the end point projected so that it is in line with the end wall. The end wall is clearly seen in the purple points in this scan.  The orange end point is lined up with the end wall. Therefore, this was a very good end scan.

Intersection Point 3D Deviations Positions Form Spherical Radius True Positions

The 3D deviations for the XYZ centerline end and intersection points are also the equivalent of spherical radius true position values.  The 3D deviations shown in the XYZ grid in the Inspection Data menu show these deviation values.
