Abstract
A method for creating a concave section of glass from a glass substrate having flat surfaces includes the use of a grinding wheel and a turntable. The method includes the steps of securing the glass substrates to the turntable. The turntable is then spun to create a turntable axis of rotation. The grinding wheel is rotated about a wheel axis of rotation such that the wheel axis of rotation is perpendicular to the turntable axis of rotation. The grinding wheel and the turntable move relative to each other along the turntable axis of rotation. The glass substrate is ground by the grinding wheel contacting the glass substrate to create the concave section of glass while the glass substrate is rotating about the wheel axis of rotation and moving relative to the turntable.
