Solution

Constrain the parts in the same manner as they are constrained in the vehicle, by using the Laser Tracker to:
  • Measure the registering points on the part
  • Manipulate a best fit of the design points and measured points
  • Scan the parts, particularly paying attention to:
    • Areas of large surface variations
    • Centres of holes
    • Centres of anchor holes & slotted holes
    • Key interface points on the plot
The scanner will display in real time the variations between the part and CAD Model by a series of different coloured needle point plots.

Benefits

The areas where the CAD Model need to be patched can readily be identified and additional data taken if required.
