Embodiment Construction

[0026] The present invention can be better understood from the following examples. However, those skilled in the art can easily understand that the content described in the embodiments is only for illustrating the present invention, and should not and will not limit the present invention described in the claims.

[0027] Such as figure 1 As shown, the bimetallic arc additive manufacturing method of the present invention specifically includes the following steps:

[0028] Step 1, import artifacts ( figure 2 ) digital model file (stl 3D file), a block;

[0029] Step 2, import the designed template structure - honeycomb template ( Figure 4 ) data (point cloud file), each slice in the present embodiment uses this template structure;

[0030] Step 3, perform layered slices on the digital model of the workpiece to be printed according to the Z direction (the layer height h of each slice has been determined), and obtain the cross-section of each slice, with a total of M layers;...

Abstract

The invention discloses a bimetal arc additive manufacturing method. A to-be-printed workpiece digital model is input into a computer, and template structure data of each layer of designed slice are input into the computer; the workpiece digital model is layered and sliced in the direction Z, the cross section of each layer of section is obtained, and the total number of the layers is M; accordingto the cross section of each layer of section of the workpiece, linear filling paths of the section of the layer are calculated and generated; the template structure corresponding to the section of the layer is compared with the range of the section of the layer, and if the template structure overall covers the cross section of the section of the layer, the next step is executed; and crosspointsof all the linear filling paths generated by the Nth layer of section and each side of a polygon of the Nth layer of template structure corresponding to the Nth layer of section are calculated, and the crosspoints are switching points of metal welding wires A and metal welding wires B on the linear filing paths. By means of the method, two kinds of different metal welding wires can be adopted forcarrying out regular or irregular alternate filling and cladding.

Description

technical field [0001] The invention relates to a bimetal arc additive manufacturing method, which belongs to the technical field of metal welding processing. . Background technique [0002] Arc additive manufacturing is a manufacturing method that melts and deposits metal layer by layer to form a workpiece by welding. The traditional arc additive process usually uses slicing software to perform layered slicing and path planning on the digital model of the parts in the Z direction, and then outputs the program to the welding robot for additive operations. At present, the dual metal arc additive manufacturing only changes the filling direction of the interlayer filling line and fills two different metals according to the fixed ratio of the filling line through software. When the two metals in the workpiece need to be filled regularly or irregularly alternately, only changing the filling direction of the interlayer filling line and the filling ratio of the two metals in the ...
