Abstract

The invention provides an ultra-precision polishing and shape error compensation method for a non-spherical surface. By the adoption of the ultra-precision polishing and shape error compensation method for the non-spherical surface, high-precision shapes and better surface machining quality can be achieved through numerical-control machining of a non-spherical optical lens mold. According to the technical scheme, the ultra-precision polishing and shape error compensation method for the non-spherical surface comprises the steps that firstly, a numerical-control machining code is generated according to machining parameters and machining tracks and is input to a multi-shaft machining tool to polish a workpiece; secondly, after polishing, the surface shape precision of the machined workpiece is measured in situ through a high-precision in-situ detection device of the multi-shaft machine tool; and thirdly, whether the measurement result meets preset shape precision or not is judged, and ifyes, polishing is ended.

Description

technical field [0001] The invention relates to the field of optical element mold polishing, in particular to an aspheric ultra-precision polishing and shape error compensation method. Background technique [0002] The traditional aspheric optical glass lens manufacturing generally adopts the mechanical processing method of material removal, which is processed through more than a dozen processes such as rough grinding, fine grinding, polishing, and edging. The manufacturing cycle is long, the processing accuracy is unstable, and the production efficiency and process Stability cannot meet the needs of the rapidly developing industry. Therefore, in recent years, a new type of molding technology for glass optical components has been developed, which uses high-precision optical molds to directly press and form ultra-precision glass optical components through heating and pressure, thus creating a large-scale and high-efficiency manufacturing of glass optical components. new era....
