Abstract

The problems of modern technology for processing lenses for optical devices are noted. Among these problems, the temperature deformation in the process of blocking with adhesive resin has the greatest effect on the quality of parts. It is substantiated that this problem can be solved using a technology that allows simultaneously processing both surfaces of the lens blank when it is fixed to the non-working surface using a photopolymer resin that hardens under the influence of ultraviolet radiation. A scheme of a device for implementing the proposed technology for processing parts with executive spherical surfaces, in particular lenses, with their vertical orientation in the processing zone, which improves the distribution of the abrasive suspension during shaping and thereby increases the intensity of stock removal, is proposed in the paper. Mathematical modeling of the nature of the processing of spherical surfaces of parts of optical devices under the conditions of a power circuit has been performed and a formula has been obtained for calculating the friction paths in the zone of contact between the tool and the surface to be machined. The use of this expression makes it possible to identify the optimal modes of lens shaping, which provide satisfactory quality and the level of intensity of stock removal.
光学零件加工的先进技术
指出了现代光学器件透镜加工技术中存在的问题。在这些问题中,粘接树脂堵塞过程中的温度变形对零件质量的影响最大。这一问题可以通过一种技术来解决,该技术允许在透镜毛坯固定在非工作表面时同时处理两个表面,使用在紫外线辐射影响下变硬的光聚合物树脂。本文提出了一种装置方案,用于加工具有执行球面的零件,特别是透镜,其在加工区内具有垂直方向,这改善了成型过程中磨料悬浮的分布,从而增加了去除坯料的强度。本文对电源电路条件下光学器件零件球面加工的性质进行了数学建模,得到了刀具与待加工表面接触区域摩擦路径的计算公式。使用该表达式可以确定透镜成形的最佳模式,从而提供令人满意的质量和去除库存的强度水平。
