METHOD FOR 3D PRINTING ON CNC EQUIPMENT WITH INTELLIGENT OPTIMIZATION OF MODES Russian patent published in 2019 - IPC B33Y10/00 B22F3/00 

FIELD: metallurgy.

SUBSTANCE: method includes billet formation by electric arc surfacing in medium of protective gases from layers consisting of metal surfaced beads contacting each other, and finish machining of formed workpiece by removal of excess metal using blade tool. All motions of equipment units are coordinated by CNC system. CNC includes control program containing specified surfacing modes for formation of workpiece. Data of the three-dimensional printing process when forming the workpiece is fixed by means of a fixing equipment complex, comprising a visual control system of the deposition zone of the workpiece, which is configured to illuminate the deposition zone with ultraviolet radiation, radiation filtration, coming from welding-up zone, and obtaining image of welded-up area, system for fixing acoustic signals from formed workpiece, laser system for measuring temperature of welding bath, monitoring system of protective gas supply and its concentration in the printing zone, welding torch movement speed measurement system and surfacing speed of surfacing wire and current measurement system, value and frequency of welding pulses, which is made in form of a single system connected through analogue-to-digital converters with CNC system by means of built-in high-performance computing modules using nVidia CUDA technology or its analogues and neural network of deep training, providing feedback for optimization of modes of electric arc-welding facing in process of three-dimensional printing. Said neural network is configured to autonomously make a decision on optimization of welding surfacing and generation of commands to change parameters of equipment with numerical control.

EFFECT: invention relates to a method of making an article by three-dimensional printing of an electric arc surfaced on CNC equipment.
