Abstract
This paper discusses an approach to the development and modeling of production processes for manufacturing items from polymeric optical materials. It describes the processes of computer-aided manufacturing in a distributed integrated medium based on a data-control system. The results of a study of how the design-and-production factors affect the optical properties of a lens are presented. The injection-molding process is studied by numerical methods in a computer-modeling program, as well as by experimental means. This paper describes how the factors associated with the gating design and the packing pressure affect the accuracy of the resulting optical item’s shape and the refractive index of the polymeric material, and how the material-supply rate into the mold affects linear shrinkage and birefringence. Testing the optical properties of the finished items confirmed that the resulting characteristics matched the requirements.
