  • Method for bore chamfer measurement
    Patent number: 8570537
    Abstract: A method for bore chamfer measurement includes providing a wheel with a surface having a bore and chamfer surrounding the bore. A light emitting device is aimed at the bore, the chamfer and a portion of the surface of the wheel adjacent to the chamfer. A light from the light emitting device is emitted to the surface of the wheel at the bore and the chamfer such that at least a portion of the light is emitted in a direction that is aligned with a center of the bore. Reflected light is detected from the surface adjacent to the chamfer and the bore. A two dimensional image of the surface and the chamfer is produced and is used to determine a dimension of the chamfer.
