针对高陡度非球面光学元件的内凹面抛光难题,提出了一种内凹面磁流变槽路抛光方法。设计与待加工内凹面形状匹配的凸模,并在凸模上开出供磁流变液循环通过的槽路,当磁流变液经过设有磁场的区域时发生流变作用形成柔性抛光磨头对内凹面产生材料去除作用。通过工件的旋转和外部磁极的移动完成对整个内凹面的抛光加工。建立了实验平台并开展了相关初步实验和分析。结果表明该方法能够适应内凹面抛光加工的需要,可获得较高表面质量,具有一定的可行性和应用潜力。
In order to solve the problem of inner concave surface polishing of high-steep aspheric optical components, a method of inner concave surface MR flow path polishing is proposed. Design and processing of the concave surface matching punch, and in the punch out for magnetic rheological fluid circulating through the tank, when the magnetic fluid through the magnetic field when the region has a rheological effect of the formation of flexible polishing mill Head on the concave surface material removal effect. Through the rotation of the workpiece and the external magnetic pole to complete the entire concave surface of the polishing process. Established the experimental platform and carried out the relevant preliminary experiments and analysis. The results show that the method can meet the needs of the concave surface polishing process, obtain higher surface quality, with a certain feasibility and potential applications.
