Inspection of bearing shells
Bearing shells are manufactured in large quantities, also for the automotive sector. Whereas the production has been extensively automated, quality assurance still relies on workers who manually sort out tested parts with surface defects and blow-outs or parts not belonging to the batch. Previous attempts at automation failed due to the many different types of bearing shell. These problems gave rise to the demand for an automatic and versatile system for inspecting different types of sintered bearing shells. Measurement technique using camera systems The basic features of a defect which can be used for the assessment of passed and failed parts are on one hand the geometrical deviation of the shape of the component and on the other hand variations (intensity, contrast, dispersion) of the reflected light energy from the regular surface structure of a passed part. The width and the length of the defect are available as the geometrical parameters for the classification of defects.
