at more than:
14. An HP rotor can be measured in about 4−5 hours with the Faro arm.
Toshiba High Pressure Rotor Replacement
14
15. Fast & Accurate Measurement
of Steam Turbine Components
HP or LP Rotor 4 to 5 hours
HP Upper Outer Shell 4 to 5 hours
HP Lower Outer Shell 8 hours
HP Inner Shells 5 to 6 hours each
N1 – N3 Gland Housings 1 to 2 hours each
LP Lower Shell 8 hours
LP Hood 3 to 4 hours
Under ideal conditions

17. Generator Measurement Examples
18
Stator Bars –
scanned and
surfaced
Scanning the stator produces
a “Point Cloud” model of the
core which can be sliced for
dimensioning.
18. Generator Measurement - Faro Arm Work
19
MIS completes
stator scanning
and Faro Arm
work in about
16 hours.
Rotor – 8 hours.
20. Nuclear Experience
23
Dressed out to
measure the
flatness on the
SONGS U2
steam generator
tube sheet.
MIS technicians have been Rad Worker qualified many times and have been trained in
Dress Out, ALARA, FME, Confined Space, Fall Protection and more.

• Catch interference problems
• QC mating parts before assembly
• Get accurate measurements without assembly
“I see some
interference
there”

28. Hydro Power Example at Big Creek
Problems
1. Unit had history of thrusting
2. Rotor rubbed at top of stator coils causing a fire
3. Needle valve / water jet was not set for optimum efficiency
Solutions
1. Set bearings at the same elevation
2. Lower rotor and center in stator coil bore
3. Measure needle valve to set water flow to correct pitch
diameter on Pelton wheel buckets
31
29. Hydro Power Example at Big Creek

Objectives
• Accurately Record Elevations of
all Horizontal Joints
• Measure Nozzle Waterflow to
Pelton Wheel contact Point
Measurements were taken with
Laser Tracker.
Waterflow line projected to Pelton
Wheel with accuracy of .030”
30. Big Creek Measurement of Horizontal Joint
& Shaft Elevations
33
Measured and
recorded the heights
of the bearing and
generator horizontal
joints compared to an
elevation datum.
Measured and
recorded the shaft
heights at the
bearings compared to
an elevation datum to
determine reason for
thrusting.
31. Hydro Oil Seal Modification

Oil seal easily measured with
Faro Arm Portable CMM.
42. Field Services and Shop Support
Examples

Diaphragm Alignment on
Outside Unit in Los Angeles
Laser Tracker uses
“Line of Sight” Measurements
43. Fast and clear reporting features in Verisurf – Deviations and Whisker Plot
This report shows the lower bearing deviations on both the TE and GE ends.
46
45. Horizontal Joint Evaluation
The points and shell outline
were taken in about two hours.
The report deviations and formatting
take only a couple minutes.

47. This circulation pump
was too big to setup on
the horizontal boring mill.

The laser tracker measured the
mill table and spindle. The
pump bore was aligned to the
mill coordinate axes.
