Additive and subtractive composite 3D printing equipment and method for plasma multi-axis numerical control machine tool

Abstract

The invention discloses additive and subtractive composite 3D printing equipment and method for plasma and multi-axis numerical control machine tool. The additive and subtractive composite 3D printing equipment comprises a central control system, a sealed forming chamber, a five-axis five-linkage numerical control machining device, a microbeam plasma gun, a cooling machine, a powder storage tank, a vertical mill milling machining device and a protective gas bottle. The vertical mill milling machining device is arranged in a III region inside the sealed forming chamber and used for cutting a layered profile of a workpiece and protrusions on the surface of the forming face. The five-axis five-linkage numerical control machining device is arranged in a II region inside the sealed forming chamber and used for changing the workpiece and machining any forming face. The microbeam plasma gun is arranged in an I region inside the sealed forming chamber for manufacturing additive. The central control system is connected with a five-axis five-linkage numerical control machining platform, the powder storage tank, the cooling machine, the microbeam plasma gun, the vertical mill milling machining device and a facing cutter. According to the additive and subtractive composite 3D printing equipment and method, after multiple layers are machined through microbeam plasma arc, the microbeam plasma arc machining is converted into milling, the protrusions on the surface of the workpiece are cut precisely at a high speed, and the internal surface quality of the workpiece is improved.

Description

technical field [0001] The invention relates to the field of micro plasma arc (micro plasma arc) additive manufacturing, in particular to a plasma and multi-axis numerical control machine tool additive and subtractive composite 3D printing equipment and method. Background technique [0002] When the plasma transfer arc current is below 15A, it is usually called micro-beam plasma arc. The power of this arc is very small, usually below 1kW, and it is one of the ideal heat sources for precision welding. The arc diameter is about 1.5mm, and the length can reach more than 5mm. [0003] Micro-beam plasma arc powder cladding rapid prototyping process is a metal direct forming process of welding arc. It draws on the idea of ​​"discrete and stacking" in the rapid prototyping method, and is similar to the basic principle of the laser rapid prototyping method. Micro-beam plasma arc powder cladding rapid prototyping uses a small current plasma arc as the heat source, through the fuse ...
