End-Scan Using the End Wall

How to perform the end-wall end scan. Back to VTube-LASER

Why the End-Scan technique is important

This end-scan method is useful for increase in precision over the scissor method. We recommend this for increased precision where high-reflectivity and burrs are not an issue on the end wall of the tube. The End Wall method is also very useful for thicker wall tubes. For tube walls with high-reflectivity and burrs, we recommend the most precise End-Scan Using End Targets.

Measure Setup

Set System Options, Measure 2 Tab, "Maximum Number of LLP Points in String" to 3 Set Measure Setup - LASER Tab: The LASER defaults to ON for CYLINDERS and END-SCANS. Set Measure Setup - LASER Tab: Cylinder stripes = 3 to 5 Set Measure Setup - LASER Tab: End-scan stripes = 5 Set Measure Setup - LASER Tab: Split bend stripes = 5 Set Measure Setup = Scan Rates Tab: Set all rates to TIMER for all scan types. Set Measure Setup = Scan Rates Tab: Set the Scan Rates TIMER is set to 0 for all TIMERS.

How To Use This End-Scan Technique

Align the scanner at the end wall of the tube. Press the green button until VTube-LASER is finished scanning all the end stripes. The advantage of this method is that it is easy to use. The disadvantage is that it is more prone to outlier points from the inner diameter surface.

Another Way to Use This End-Scan Technique

Align the scanner so that it touches one end wall of the tube. Press the green button until VTube-LASER is finished scanning all the end stripes. The advantage of this method is that it is less prone to outlier points. The disadvantage is that it is hard to aim at thinner walls.
