Tube Measurement - By Cylinders Method in CAM2

Preparation

• Mount / fix the tube / pipe firmly within reach of the FARO^® device (FaroArm /Laser Tracker)
• Establish the Start and Finish end faces.
• Identify the cylinders (straight sections) to be measured
• Key-in nominal tube data if available. (Key-in – Tube)

Measurement

From the Measurement ribbon select Tube by Cylinders (also via Home - Measurement gallery).

• The Tube properties window will be shown:
  1. Name and Comments can be entered
  2. Override Diameter
     • check to enter tube diameter.
     • uncheck to use measured value.
  3. Starting Plane
     • Choose an existing start plane or Define to measure a plane.
  4. Ending Plane
     • Choose an existing end plane or Define to measure a plane.
     • Plane calculation methods: There are 3 methods to fine-tune tube length:
       • None - best fit plane from readings
       • High Point - highest plane reading (maximizes tube length)
       • Low Point - lowest plane reading (minimizes tube length)
  5. Nominal - select Nominal Tube if available. This will also automatically align the Measured and nominal tubes, providing comparison data.
  6. Default Bed Radius - enter default bend radius This is normally detailed on the component drawing with the tube / pipe bend data.

• Click Create to start measurement.
• The Measurement window will show prompt to Measure Tube - Start plane.
  • Probe a minimum 3 points on start plane of the tube using the green button / G key.
    
• The Output window will then prompt to Measure Straight Segments.
  
• Probe a minimum 6 points (cylinder) on each straight section using the green button / G key.
  

Note: Ensure not to probe on the bends, and end each straight using the red button / H key.

• Once all the straights have measured, press the red button again, to indicate that there are no straights remaining.

• The Measurement Window will prompt to Measure Tube - End plane.
  • Probe a minimum 3 points on End plane of the tube using the green button / G key
    
• If a nominal tube was selected in the Properties window, the measured tube will automatically be aligned using all breakpoints (best fit) and compared to the nominal tube.
