Abstract
The paper considers the technology of manufacturing flange parts using local methods of metal forming. Various technologies of manufacturing of ring blanks for the subsequent rotary forging of flanges are offered and investigated. On the basis of computer simulation, the main dimensions of the workpiece have been chosen, providing the best forming parts and the parameters of the technology mode. The results of experimental studies have shown that this technology is possible to manufacture flanges according to EN 1092 using the process of axial rotary forging with cylindrical rolls. The use of local methods of deformation of metals allows expanding the possibilities of technological processes at lower power equipment.
