Abstract
A blocking technique and apparatus are used to mount a partially finished lens or other component to an arbor, which is useable to hold the partially finished lens for subsequent machining or mechanical operations. The blocking of the partially finished lens occurs on the same axes of the multi-axis machining device that were used to generate the partially finished lens. The blocking of the partially finished lens occurs without removing the partially finished lens from the workpiece holder which held the partially finished lens during the machining operation. Accurate and repeatable blocking is achieved using the axes of the lens generating equipment.
