Additive technology to create a tool for electroerosive processing

Abstract

The paper considers new methods and tools for combined electroabrasive finishing of metal parts, and shows the advantages of such a tool over traditional methods of finishing shaping the surfaces of labor-intensive products made of difficult-to-process alloys. The possibilities of layer-by-layer application of materials using additive technology to reduce labor intensity and cost for combined processing of tools with layers of abrasive on the periphery of a metal body obtained from a low-melting alloy by the additive method are considered. The possibility of accelerated production of tools using this technology, which does not require significant costs for editing and sharpening for specific parts, is shown, which reduces the production time of technological equipment when launching new generations of products, primarily in the aerospace industry of mechanical engineering. The new method and design of the tool are protected by a Russian patent. Experimental operation of wheels made using additive technologies has shown that the use of such a tool in single and small-scale flexible structure production significantly reduces the complexity of manufacturing parts for finishing operations.
