K9APE® Machine Vision Inspection System For
Flat Surfaces
K9APE® Machine
Vision Inspection Systems are readily adapted for inspection of precision parts
with flat surfaces - such as those that mate or seal to another component. Inspection
can occur during or after the manufacturing process.
The images shown below are from a 9 inch (229
mm.) x 3-3/4 inch (95 mm) cast transmission manifold. The image illustrates a
portion of the transmission's hydraulic circuitry and its land seal surfaces.
The land seal surfaces mate with the transmission body and must be free of
defects that would allow pressurized hydraulic oil to leak.

Transmission
Manifold Machined Casting
High-resolution images of the sealing
surfaces of transmission manifolds were captured with our K9APE®
Machine Vision Inspection System. A highly compressed image of the manifold
land seal surface of a typical part is shown below.

Small defects that could readily escape
notice by human inspectors were readily detected on uncompressed images.
Each of three example images shown below has
been cropped from a full image of the part - as shown above. Full images (even
in compressed format) are too large to download conveniently on the web.
The first example is an image of a small
casting defect or indentation in the sealing surface. The specification for the
land seal width is 3 mm. At the point of defect, the seal width for this part
is only 2 mm.

The second example is an image of a small,
thin fracture on the top of the land seal that occurred during machining. The
depth of the fracture is estimated at 0.25 mm.

The third image exposes a fracture in the
sidewall of the land seal that caused a broken edge. The fracture extends down
~ 1 mm. at its deepest point, at the left side of the broken edge. The broken
edge is ~ 4 mm. long. The land seal also contains a small chip measuring ~0.75
x 1 mm. by ~0.1 mm. deep.

These images were captured with an EPIX®
PIXCI® Model D Imaging Board.
EPIX® XCAP™ Imaging Software was used for image formatting. The original files
have been JPEG-compressed for display here.
Manufacturing defects are readily detected
and measured by our K9APE® Machine Vision Inspection Systems. Images
better than JPEG-compressed quality can be obtained during manufacture.
