Soft Foot Evaluation

The Soft Foot evaluation provides you with a sense of severity without showing
numbers. Numbers are not used because,

most of the time, they are mistaken for the value

of the shims

(totally wrong). When the numbers are calculated, they are compared

against the tolerance (usually 0.5 mils/inch). If a particular foot is below the toler-
ance, it is labeled OK. If the number is between one and two times the tolerance, it
is labeled with a single X. If the number is between two and three times the toler-
ance, it is labeled as XX. If the number is greater than three times the tolerance, it
is labeled as XXX (the more X’s, the greater the severity).

The number is evaluated by taking the horizontal and vertical movement on each
target and calculating the total movement on each target. The largest movement
of the two is then divided by the distance between the heads (dimension C) to
determine the angle of deflection caused by loosening a hold-down bolt. This
angle is compared to the tolerance for final evaluation for that foot.

The advantage of this method is that it uses a combination of horizontal and ver-
tical movements on the target to determine the problem feet. Experience has
shown that approximately 20% of the soft foot conditions cause a horizontal move

because of a severely bent foot

.

Note

The tolerance can be changed in UltraMgr and downloaded to the
analyzer. See “Tolerances” on page 3-193 for more information on
loading tolerances to the analyzer.

FDI Evaluation

The Frame Distortion Index provides you with a sense of severity

with numbers

.

Caution!

Do not mistake these numbers for shim values.

When the numbers are calculated, they are compared against the tolerance (

usu-

ally

excellent <2 mils and acceptable <3 mils). If a particular foot is in the excellent

range, the number is plain. If the foot is acceptable, it will have a clear box around
the number. If the foot is out-of-tolerance, it will have a solid box around the
number. The higher the number, the greater the severity.
