About VTube-LASER End Engle Qualifications

Sample Print

The end angle deviation is the total angle the measured centerline end length varies from the master end length in degrees.

VTube-LASER includes end-angle qualifications because GMC used to include +/- 1 degree for the end-length qualification.

However, it is our opinion that this qualification is redundant because the end lengths are already qualified in the tangent-midpoint-tangent grid. In general, it is better to qualify a tube shape using linear units than polar (angular) units.

Set the Datum

It's necessary to set the datum using the Datum tab in the MASTER DATA menu.

It may also be necessary to rotate the master tube into the an orientation that is similar to the print. In this case, we used the Transform feature to rotate the master tube so that the first leg is aligned to the Y axis.

Datum Reports

After a measure and alignment, use one of the Datum reports in the report menu to show the dimensions.

In this example, the two X values show the dimensions that correspond to the 5.5 dimension.
