ABSTRACT:
A three axis, computer controlled apparatus for edging optical lenses maps the surfaces of a lens blank along a path defining the shape of the lens to be cut from the lens blank and from which mapping a computer controlled cutting algorithm directs the movement of the lens in the R, Z and theta axes direction. The apparatus provides rough cuts, finished cuts and automatic placement of bevels and grooves along the edge of the lens with minimal operator intervention.
