Solving the Problem of Abrasive Machining in the Production of Rocket and Space Technology Details

Abstract

details of rocket-space technology of complex geometry for ideal work require roughness of the surface layer Ra = 0.09 - 0.31 µm , which is not achieved by the applied processing methods and the requirements of the design documentation are not reached. The use of traditional methods of finishing causes the unreliability of certain components and parts of rocket-space systems (RKS) are operating in extreme conditions. Abrasive-extrusion processing of parts provides the conditions for design documentation on the surface roughness of parts of rocket and space technology. The best conditions for the treatment process were determined when using nitro lignin as working mixture, and an economic analysis was made of this treatment method compared with the methods used. The project demonstrates acceptable performance, net income and net present value are positive.
