SHAPING A GLASS SUBSTRATE AFTER CUTTING

A method includes projecting a first energy beam onto an annular edge of a glass substrate. A first portion of the annular edge of the glass substrate is removed with the first energy beam. Removing the first portion increases the roundness of the annular edge of the glass substrate. A second energy...

Zusammenfassung:	A method includes projecting a first energy beam onto an annular edge of a glass substrate. A first portion of the annular edge of the glass substrate is removed with the first energy beam. Removing the first portion increases the roundness of the annular edge of the glass substrate. A second energy beam is projected onto the annular edge of the glass substrate. A second portion of the annular edge of the glass substrate is removed with the second energy beam. Removing the second portion increases the roundness of the annular edge of the glass substrate.
