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 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. (Set the Offset "AWAY" if the tube end is moving into a surface.)

• Align the scanner with a slight scissor angle across the end as is shown in the image on the right
  
  
• Attempt to hold the laser motionless when collecting the stripes across the end to increase repeatability.
  
  
• Consistently place the line across the same area of the tube end from measure to measure.
  
  
• Press the green button until VTube-LASER is finished scanning all the end stripes.
