Displacements (in addition to already identified misalignments from the project requirements):

  • +/- 400 mm along X
  • +/- 400 mm along Y

 

Rotations (in addition to already identified misalignments from the project requirements):

  • +/- 2.0o around X
  • +/- 2.0o around Y

 

Axis convention:

 

Considered combinations:

  • + 2.0o around X associated to -400 mm along Y
  • - 2.0o around X associated to +400 mm along Y
  • + 2.0o around Y associated to +400 mm along X
  • - 2.0o around Y associated to -400 mm along X

 

Sensitivity performed on the worst case only:

  • 400mm replaced by 300mm
  • 2.0o replaced by 1.5o
