Abstract:
A method for varying a radius of an optical quality surface of a casting mold formed in a tooling cavity, the tooling cavity at least partially defined by an optical tool having an optical quality surface of a given radius, includes imparting a compressive stress within the optical quality surface of the casting mold to predictably decrease the radius of the optical quality surface of the casting mold.
