Description

technical field [0001] The invention relates to the technical field of precision machinery manufacturing, in particular to a compound manufacturing process equipment of adding and subtracting materials. Background technique [0002] The precision manufacturing of complex parts is an urgent problem to be solved in my country's aviation, aerospace, precision mold and other industries. Taking mold parts with internal cooling channels as an example, not only must the shape accuracy of the cavity and flow channels be guaranteed, but also high requirements are placed on the surface quality of the mold cavity and flow channels. The traditional manufacturing method is For milling of the entire blank, the complex cavity is generally processed by a five-axis machine tool, which has high equipment costs, a large amount of material removal, and a large amount of cutting fluid is used during the processing, which is not conducive to environmental protection. Another manufacturing method ...

Taking mold parts with internal cooling channels as an example, not only must the shape accuracy of the cavity and flow channels be guaranteed, but also high requirements are placed on the surface quality of the mold cavity and flow channels. The traditional manufacturing method is For milling of the entire blank, the complex cavity is generally processed by a five-axis machine tool, which has high equipment costs, a large amount of material removal, and a large amount of cutting fluid is used during the processing, which is not conducive to environmental protection. Another manufacturing method is to use Additive manufacturing methods, such as laser selective melting (SLM), melt metal powder layer by layer in selected areas. The shape accuracy of parts manufactured by laser selective melting can be as high as 0.1mm, but the surface roughness is not ideal. Mold parts manufactured by this method often require post-processing such as milling and polishing on specific surfaces, and the parts need to be clamped again, resulting in accuracy errors and time costs
