Abstract

Glass molding press is an efficient manufacturing technology to fabricate microstructures on glass. To optimize the experimental conditions for precision replication of periodic microstructures with different pitch sizes, Finite Element Method (FEM) simulation and experiments were carried out to study the glass molding press process. First, the effects of the change in pitch size on stress and geometrical replicating accuracy were evaluated. Thereafter, glass molding experiments were carried out to form microstructures on the glass surface, and the molded microstructures were measured. By comparing the simulation results with experimental results, the FEM simulation was experimentally verified, and the optimal machining conditions were obtained and discussed.
