Influence Factors and Optimization Simulation Analysis of Molding Pressing Annealing for Aspherical Lens
The annealing process is an important process in optical glass molding,and the factors that affect the an-nealing process mainly include annealing speed,holding force,and holding time.Using finite element simulation meth-od and orthogonal method,the influence of three main process parameters on the annealing process of aspherical lens-es was analyzed in detail.Finally,multi-objective process parameter optimization was obtained through grey correlation analysis,and the optimal combination of each process parameter was determined.
