Claim:
1. A method of shaping the edge of a glass plate comprising: coupling a glass plate to a support fixture, a portion of the glass plate extending from the support fixture a distance L and comprising a first surface, an second surface opposing the first surface and an end surface, and wherein the first surface and the end surface intersect along a first edge and the second surface and the end surface intersect along a second edge; contacting the first edge with a first abrasive cup wheel rotating about a first axis of rotation angled relative to the first surface, wherein the first abrasive cup wheel contacts the first edge with a first force F contacting the second edge of the glass plate with a second abrasive cup wheel rotating about a second axis of rotation angled relative to the second surface and spaced apart from the first abrasive cup wheel axis of rotation by a distance D equal to or greater than 220 mm, the second abrasive cup wheel contacting the second edge with a second force F producing relative motion between the first and second abrasive cup wheels and the glass plate during the contacting of the first and second abrasive cup wheels with the first and second edges, respectively; and wherein the first deflection does not overlap the second deflection.
