FIELD: additive manufacturing technology.
SUBSTANCE: invention relates to an apparatus for growing a part by means of additive-subtractive-hardening technology and can be used in various fields of mechanical and aircraft engineering, as well as the rocket and space industry. The additive module of the apparatus using subtractive transitions for mechanical treatment of basic connecting surfaces between the transitions of growing parts of a detail of a complex shape, access whereto after the synthesis of the entire part is hindered or impossible, has two or more surfacing units and two sources of concentrated energy flow, respectively. Each surfacing unit supplies similar or different metal material to the growing area. To ensure stability of the growing process, an oscillator is used allowing to ignite an electric arc without contacting the surface of the detail and to maintain combustion required for surfacing layers of the metal material. The additive module has an automated control system for supplying metal wire in three coordinates for each surfacing unit.
EFFECT: technical result consists in expanding the technological capabilities of the additive-subtractive-hardening technology, increasing growing productivity and improving the quality of the grown metal.
