Extra Area Concept (Aluminum Blisters)
The system will regard this object
as “foreign” if it increases the
“extra area” around the object
beyond the Extra Area % setting.*
*If the color of the foreign object has been taught, it will be detected if its area exceeds the
Min. Area (not Min BG Area ) setting.
Lighting conditions may normally cause a slight
shadow, which the system would detect as a
“hole” in the pocket color. The Extra Area %
setting can be adjusted to accommodate this.
The system will always regard this “hole” in
the background color as “foreign” material if
its area is larger than the Min. BG Area setting.
Objects
When you pick the Extra Area % menu item, an Extra Area % slide bar
appears. Use the cursor to select any extra area value between 0% and
1000%. When you move the cursor up or down, the value in the
Extra Area
% menu item changes accordingly.
Define Tolerances
From the Define Tolerances menu, shown in Figure 6.8 (page 6–9), you
can control the amount by which the position, area, and shape, of objects can
vary and still pass inspection. When you click on one of the tolerance
adjustment menu items –– for example,
Min. Area –– a slide bar and cursor
appears, as Figure 6.8 illustrates.
As you move the cursor up or down, the value appearing in the menu item
varies up and down accordingly. To increment (or decrement) the value by
one, click on the top (or bottom) micro–adjust button once for each change.
