Electron beam strand coaxial fuse wire deposition forming method

Abstract

The invention relates to an electron beam strand coaxial fuse wire deposition forming method. The method comprises the steps that on the basis of three-dimensional modeling software, a component three-dimensional model is constructed and converted into an STL format file to be input into an electron beam rapid forming system; data processing software conducts layering slicing treatment on the component three-dimensional model which is in the STL format, and the thickness of each slice layer is set; based on an electron beam fuse wire machining method and each slice layer, the filling path andthe filling angle of each slice layer are generated to serve as the fuse wire deposition forming stacking path; electron beam current parameters, wire feeding parameters and motion parameters are input into the electron beam rapid forming system, the electron beam strand coaxial fuse wire deposition forming machining procedure is generated, metal wire and electron beam current coaxial conveying needs to be kept in the forming process, and a metal wire is melted and continuously stacked under the action of the electron beam current. According to the stacking method, layer-by-layer fuse wire deposition is conducted according to the fuse wire deposition forming stacking path till a component conforming to the three-dimensional model is formed.
