4.7.14 Smart Edge (Circle)
(Available from Ver.1.6)
What is Smart Edge (Circle)?
Smart Edge (Circle) is a function to output the center point, radius or diameter of a round object by detecting
edges of the object with a number of cells. It is suitable for the detection of a missing edge and burr of a round
object, angle of a convex (or concave) part, the inspection of circularity and the calculation of the angle of the
diameter position of an ellipse. For a ring-shaped object, detecting the outer and inner circles both enables the
detection of the difference between the centers of the two circles or the ring width.
The central coordinate or radius of a circle can be also detected when a whole object cannot be captured or for
the angle of a chamfered object.
Inspection example
•
Detection of radius,
diameter
•
Detection of angles
of measured
maximum and
minimum values.
•
Capturing only a
part of a circle can
detect the circle.
•
Ring width and
center points of
inner and outer
circles
Detect Mode Output Data
Measure Radius Detects the radius from the center point
of a detected virtual circle to the edge.
This mode is effective to detect a
missing edge and burr, and the position
and angle of a projection as the left
figure.
Circularity inspection is also performable
based on a radius value.

Measure Diameter Detects the diameter based on the edge
coordinates of a circle detected with two
opposite cells .
Circularity inspection is also performable
based on a radius value.
Measure Width Inspects ring-shaped objects. Measures
the difference between the edges of
outer and inner circles, and outputs it as
"Width". This mode is suitable for
inspecting the misalignment of center of
concentric circle as the central
coordinates of two circles are detected.
Circularity inspection is also performable
based on a radius value.
