Algorithm for Selecting the Optimal Technology for Rapid Manufacturing and/or Repair of Parts

The subject of the study is the technology of rapid production and/or repair of parts for which there is no design documentation, in order to return them to working state as soon as possible. Such technologies are built on the basis of reverse engineering operations, with the further use of additive and extractive technologies. The work is aimed at finding the optimal technology for rapid production and/or repair of parts. To achieve the goal, schemes of technological operations have been developed according to various methods of production of parts from specified metals and the mass of the workpiece. The labor intensity of work for each technological operation of part production and the total labor intensity of work in the manufacture of a single part and a batch of parts are calculated and compared. An experimental study of the production of the part using reverse engineering technologies, additive and extractive technologies was carried out, and different methods of its production were compared according to the parameter of labor intensity. An algorithm for selecting the optimal technology for rapid manufacturing and/or repair of parts is proposed, provided that labor intensity and manufacturing time are minimized, taking into account the accuracy and volume of manufacturing.
