To suppress the mid-high-frequency error of small optical tungsten carbide aspheric molds, it is proposed to quickly select the critical process parameters by simulating the residual error after convolution of the tool influence function (TIF). After polishing for 10.47 min by the TIF, two simulation optimizations, RMS and Ra, converge to 9.

- Traditional polishing methods struggle with small aspherical molds due to tool size limitations, leading to uneven surface roughness and errors.
- The study introduces a new polishing tool—a viscoelastic polyester fiber cloth wrapped around a small steel ball—designed to adapt to the unique shapes of these molds and enhance surface quality.
- Through experiments, it was shown that this method significantly improved surface finish, reducing the peak valley measurement and surface roughness dispersion, achieving better quality control for small aspherical molds.
Precision glass molding is a revolutionary technology for achieving high precision and efficient manufacturing of glass aspheric lenses. The material properties of glass, including elastic modulus and viscosity, are highly dependent on temperature fluctuations. This paper aims to investigate the effect of elastic modulus on the high-temperature viscoelasticity of glass and the accuracy of the finite element simulation of the molding process for glass aspheric lenses.
