How to perform end-scans with a ball probe.

• Back to VTube-LASER
• See End-Scan Technique Research

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 with this method 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.)

• 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.

• 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.
  
  

• Set Part Setup - Set the A-End Diameter to the diameter where the measurement will be taken.
• Set Part Setup - Set the A-End or B-End Offset project the tube end point to the master end point location. A negative number projects toward the adjacent bend. A positive number projects away from the adjacent bend.
• 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 "AWAY" if the tube end is moving into a surface.

• Align the probe the end of the tube as shown in the diagram on top of the end surface.
