Enable Smoothing
Filter
If true, the tool removes isolated outlier points (by excluding noise
points) for the Roundness and Bounding Circle calculations, since these
calculations are sensitive to individual defect points. An isolated outlier is
one where both neighbors are not outliers.
If two points in a row are beyond outlier distance, they are still consid-
ered a defect in Roundness and Bounding Circle calculations. All outlier
points are still used in the "Percent of Points Out Of Tolerance" check.
Enable Bounding
Circle
If true, the output "Bounding Circle" is calculated. The bounding circle is
the smallest circle that includes all the points found. If Enable Smoothing
Filter is true, noise points are excluded to provide more reliable results.
If the Bounding Circle radius exceeds the Outer Bounding Radius Toler-
ance, the tool will fail.
Outer Bounding
Radius Tolerance
If Enable Bounding Circle is true, and the Bounding Circle radius
exceeds this tolerance, the tool will fail.
Enable Inscribed
Circle
If True, the Inscribed Circle output is calculated. The Inscribed Circle is
the largest circle that can fit inside all the points found.
Inscribed Radius
Tol era nce
If Enable Inscribed Circle is True, and the Inscribed Circle’s radius
exceeds this tolerance, the tool will fail.
Enable Ring Thick-
ness Check
If true, the ring’s thickness at each radial line is calculated and checked.
The tool fails if this value exceeds the Ring Thickness Tolerance. The
Ring Thickness is an output. (Circle Type must be a Ring type.)
Each individual pair of inner and outer points on a radial line is also
checked against the tolerance. If the pair exceeds the tolerance (or
either the inner or outer point is missing), it is moved to the outlier list
and added to the Percent of Points Out of Tolerance.The ring thickness
at each radial line is the "Ring Thickness List" output.
Ring Thickness Tol-
erance
If Enable Ring Thickness Check is true, and the Ring Thickness exceeds
this value, the tool will fail.
Enable Concentric-
ity Check
If true, the ring’s concentricity is calculated and checked. The tool fails if
this value exceeds the Max Concentricity Error. The Concentricity Error
is an output. The concentricity error is the distance, in units, between the
inner and outer circle centers. (Circle Type must be a Ring type.)
Max Concentricity
Error
If Enable Concentricity Check is true, and the Concentricity Error
exceeds this value, the tool will fail.
Output Name What it is
Passed If True, the found circle’s parameters lie within all the limits.
Outer Circle The found outer circle.
Inner Circle The found inner circle (Circle type is Ring).
Circle Shapelist The found outer circle as a Shapelist if Circle type is Circle. The outer
circle with an inner circle hole if Circle type is Ring.
