Abstract
A system for machining a glass workpiece comprises means for rotating the workpiece. A concentrated beam of energy is axially directed to the surface of the workpiece to soften the glass material. The softened glass material is then removed by a pointed or relatively narrow tool which is precisely located with respect to the area treated by the energy beam.
