Example Embodiment
[0041] Example 1: One figure 1 The shown method for additive manufacturing of metal parts based on curve profile features
[0042] Manufacture of parts with a single curve profile feature with constant width:
[0043] 1. Establish CAD geometric models of metal parts and extract STL models of parts;
[0044] 2. The width of the metal part model is 6.5mm and the length is 100mm. Considering that there is a certain blank margin, a sheet with a width of 7mm can be selected; according to the design of the resistance welding process, a metal sheet with a thickness of 2mm can be used. Parts with good morphology, structure and mechanical properties are obtained. Therefore, a metal sheet with a width of 7 mm and a thickness of 2 mm is used as the raw material for welding.
[0045] 3. The contour point set of the STL model is extracted and filled by the layered slicing software to generate a G code that contains manufacturing information such as feeding thickness 2mm and length 100mm and can b...

[0049] Example 2, one figure 2 The manufacturing method of metal parts based on the physical manufacturing of the parts shown
[0050] For this kind of metal parts with holes in the middle and wide width:
[0051] 1. The outer contour of the metal part model is 50mm in width, 100mm in length, and 40mm in the middle hole diameter. Build a CAD geometric model of the metal part and extract the STL model of the part;
[0052] 2. Use metal sheet with a width of 10mm and a thickness of 1mm as the raw material for welding.
[0053] 3. According to the STL model and the width and thickness of the raw material, the contour point set of the STL model is extracted and filled by the layered slicing software to generate the G code that can be recognized by the machine tool. This G code can control the movement of the workbench according to the planned part manufacturing path, that is, first control to complete the single-layer and multi-channel manufacturing of the entire part plane, and then con...

[0062] Example 3: One image 3 The manufacturing method of metal parts based on the physical manufacturing of the parts shown
[0063] Manufacturing of metal parts with local bosses:
[0064] 1. The outer contour of the metal part model is 24mm in width, 150mm in total length, 50mm in length at the two ends, and 12mm in width respectively. The CAD geometry model of the metal part is established, and the STL model of the part is extracted;
[0065] 2. Use metal sheet with a width of 12mm and a thickness of 3mm as the raw material for welding.
[0066] 3. According to the STL model, as well as the width and thickness of the raw material, the contour point set of the STL model is extracted and filled by the layered slicing software to generate the G code that can be recognized by the machine tool.
[0067] The G code can control the movement of the worktable according to the planned part manufacturing path, that is, control to complete the manufacturing of a single layer and multiple plane...
