Parameter
Description
Surface Width
The width of the surface area in which laser data is used to form the fitted surface line.
This value should be as large as the surface allows.
Surface Offset
The distance between the edge region and the surface region.
Setting a small value allows the edge within a tighter region to be detected. However, the
measurement repeatability could be affected if the data from the edge are considered as
part of the surface region (or vice versa). A rule of thumb is to set
Surface Offset
equal to
Nominal Radius
.
Nominal Radius
The radius of the curve edge that the tool uses to locate the edge region.
Edge Angle
A point on the best fit circle to be used to calculate the feature point. The selected point
is on the circumference at the specified angle from the start of the edge region.
The angle is measured from the axis perpendicular to the fitted surface line.
Edge Type
Defines the type of feature point to use for the edge (Corner or Tangent).
A tangent edge point is the point selected based on the defined Edge Angle. A corner
edge point is the intersect point between the fitted surface line and a edge line formed
by interpolating the points at and after the tangent within the edge region.
Strip
The Strip tool measures the width of a strip. Gocator compares the measurement value with the values
in
Min
and
Max
to yield a decision. For more information on decisions, see
on page 151 for instructions on how to add measurement tools.
