Embodiment 1
[0046] In this example, a gas-shielded arc welding torch is used to prepare a die-casting mold with complex cooling channels and thin-walled and thick-walled shapes. The electric current is 250A, and its specific preparation method is as follows:
[0047] S1: According to the requirements of the shape, thickness and dimensional accuracy of the mold to be formed, the 3D CAD model of the workpiece to be formed is subjected to layered slice processing to obtain the data of the layered slice, and the data of each layered slice includes the layered slice Thickness, shape and dimensional accuracy,
[0048] S2: Carry out forming path planning according to the data of the layered slices, generate NC codes for each layered slice required for forming processing,
[0049] S3: Perform fusion deposition layer by layer according to the numerical control codes of each layered slice obtained in step S2. Specifically, on the substrate, according to the digital forming processing path obtaine...
