Technological bases of high-precision machining of spherical optical surfaces

Application: processing of precision spherical surfaces of optical lenses using the complex of techno­logical processes, special tooling and equipment.

Advantages: optimization of technological process of manufacturing lenses, improving the de­sign of equipment used and tooling on the basis of this approach has improved the processing perfor­mance by 25–30 %, reduce the spoilage on 10–15 % and reduce the required skill of the workers from 6 to 3 categories.

Key features: technological bases of processing of high-precision optical components with spherical surfaces have been developed: a systematic approach to the development of manufacturing technology of optical parts are proposed, taking into account the physical phenomena occurring in the contact zone «tool-part» and the system «machine-fixture» in various stages of production. Criteria and the method of optimizing processing conditions on lapping and lapping operations are formulated; a mathematical model of tool wear and stock removal allowance of the work piece, enabling to create the design proce­dure of tools with higher dimensional resistance; the influence of hydrodynamic processes in the contact zone of tool and work piece on precision and performance of finishing operation has been considered, and proposed ways to intensify treatment.
