Abstract

With the development of optical components towards low surface damage and low scattering characteristics, more and more attention has been paid to the surface integrity of optical components. Grinding is a common rough machining process for precision optical components, and its surface quality affects the subsequent polishing efficiency and the surface integrity of optical components directly. Therefore, in this paper, studies the grinding surface morphology of ZF62 optical glass material from many aspects such as grinding wheel modeling, surface formation mechanism, and abrasive movement analysis. The paper models the grinding wheel based on the power spectral density (PSD) of the grinding wheel surface, and verifies the effectiveness of the modeling method through experiments. Basing on analyzing the surface roughness with different grinding parameters, there are conclusions as follow: The modeling of the grinding wheel surface based on PSD could effectively simulate and analyze the grinding surface of the grinding wheel. Both the simulation experiment and the actual experiment show that the consistency of the trend. The surface roughness decrease with the increasing of the grinding speed and increase with the increasing of feed rate and the grinding depth.
