METHOD AND DEVICE FOR SHAPING PLASTIC OPTICAL LENSES BY CHIP REMOVAL

摘要

A turning machine/lathe (14) has a lathe tool (LT) (16) wit its cutting edge (18) in contact with a lens (10) via its tip (20). A central navigation computer (CNC) controller creates a desired profile with the LT along required coordinate axes on a surface of the lens as it turns. As the LT twists off the surface of the lens, a turned cutting is produced where the tip contacts the lens. An Independent claim is also included for a device for
