MECHANISM AND TECHNOLOGY FOR PRODUCING SHEET METAL PARTS IN SINGLE-PIECE PRODUCTION

The paper considers a new technology for cutting out of a metal sheet with a thickness of up to 1.5 mm using one-sided and two-sided templates coated with photoresists. This technology was previously used in the radio industry and in instrument engineering, where photoemulsion was used as a coating. The paper reveals the possibilities of significantly increasing the resource when using multilayer photomasks with a new coating with various methods of its application, limits are set for the use of coatings made of photoemulsion and photoresists, depending on the purpose, complexity of the parts obtained, accessibility for the tool when moving them to the processing zone. The mechanism of controlling the vector of action of the electric field during the anodic dissolution of materials is revealed due to the limitation of the zone of its effect by photomasks for single and reusable use, the advantages of the new technology in It is used in experimental and single production of products of various complexity for the aerospace industry of mechanical engineering.
