K9APE® Machine Vision Inspection System For
Concave Surfaces
K9APE® Machine
Vision Inspection Systems are readily adapted for inspection of concave
cylindrical products - such as automobile engine crankshaft bearings.
Inspection can occur during or after the manufacturing process.
Two
63 mm. Automobile Engine Crankshaft Bearings
Nos. 3 and 4
A crankshaft bearing consists of a steel
shell that is lined with a soft metal bearing surface. The bearing surface is
finished with a broach. Typical defects include excessive removal of bearing
material that exposes the steel shell (No.3), chipped bearing surface (No. 4)
and spalled bearing surface (No. 5).
Five new 2-1/2 inch (63 mm) diameter
crankshaft bearings were mounted on a K9APE® Machine Vision
Inspection System and the following images of entire concave bearing surfaces
were obtained. Note, the aspect ratios and resolutions of the images have been
changed to accommodate viewing here.

Defect characteristics, such as in these
examples, are readily detected and measured by our K9APE®
Machine Vision Inspection Systems. Images of higher quality can be obtained
during manufacture.
