Optical Measurement of Rim Dimensions
Inspection of Car Wheel Dimension and Shape Tolerances
The quality of wheel geometry is a factor crucial to the driving comfort and safety of motor vehicles. Quality is evaluated based on functional geometric parameters for wheels’ bead seats, center bores, bolt holes and mounting flanges. Conventional methods of inspection that ascertains position, shape and orientation tolerances are predominantly tactile. Contact with scanned surfaces can affect wear and speed adversely.
On the basis of its OptoInspect 3D technology, the Fraunhofer IFF, in cooperation with industry partners, developed a non-contact measurement system that eliminates the drawbacks of tactile inspection and inspects relevant geometric parameters of car and truck wheels quickly and fully automatically.
