[PDF] Precision Complex Machining of Glass Lens Mold

The study proposes a new machining process for cemented tungsten carbide glass lens mold with Fresnel shape. The curved surfaces except for sharp edges of Fresnel shape are machined by the conventional grinding method with a disk type metal bonded diamond wheel. Then, sharp edges on curved surfaces are created by fly cutting method with knife-edged single crystal diamond tool.
