  • Method of forming a mirrored bent cut glass shape for vehicular exterior rearview mirror assembly
    Patent number: 8164817
    Abstract: A method of forming a mirrored bent cut glass shape includes bending a flat sheet of glass to establish a curved sheet of glass. A machine vision system determines a surface profile of the curved sheet of glass, and a computer numerical controlled cutting tool is positioned at the curved sheet of glass and its cutting wheel is maintained at or close to 90 degrees to the tangential plane of the curved sheet of glass. At least one of (a) the cutting wheel and (b) the curved sheet of glass is controlled in three dimensions to cut a bent cut glass shape from the curved sheet of glass, and such controlling is, at least in part, responsive to the surface profile of the curved sheet of glass. A mirror reflector is established at a surface of the bent cut glass shape to form a mirrored bent cut glass shape.
