Vtube-laser logo.jpg How to perform end-scans with a ball probe.

Why the End-Scan technique is important

This end-scan method is useful for situations where the only option is a ball probe - or where the Laser cannot reach effectively - but a ball probe can.

Using a ball probe is very precise as long as the tube is properly held with a work holder.

The main drawback is that the tube must be securely mounted without deforming the shape. It must also be touched - thereby potentially moving the tube - which will invalidate most measurements.)


Measure Setup

  • Set Part Setup - Set the A-End Diameter to the diameter where the measurement will be taken.
  • Set Measure Setup - LASER Tab: The LASER defaults to OFF for at least END-SCANS.
  • Set Measure Setup - TACTILE Tab: Uncheck the Continuous Scan on Tactile End-Scans.
  • Set Measure Setup - TACTILE Tab: Set the Offset for each end to "TOWARD BEND" if the measurement is on the end wall. (Set the Offset "AWAY" if the tube end is moving into a surface.)

How To Use This End-Scan Technique

  • Align the probe the end of the tube as shown in the diagram below - take two points per quadrant.

  • Press and release the green button for each measure.

  • It is not necessary to take all four quadrants. However, more are better if possible.

  • Press the RED button when you are finished collecting data.
