Manufacturing method of multi-scale bionic surface structure

A manufacturing method of a multi-scale bionic surface structure is manufactured in an overlaying welding mode and comprises the specific steps that a non-smooth surface of a minimum-size structure iswelded through an overlaying welding method, a position is reserved for a large structure size, and a welded structure is corrected through a grinding machine after overlaying welding; the soil touching part is surfaced with the minimum size structure again, the non-smooth surface of the second minimum size structure is welded, and the welded structure is corrected by using the grinding machineagain after surfacing to achieve the required structural shape; and the steps are repeated until the non-smooth surface of the maximum size structure is machined. According to the method, the manufacturing period can be greatly shortened, and the very excellent bionic non-smooth anti-drag surface is obtained. 一种多尺度仿生表面结构的制造方法，采用堆焊的方式制造，具体步骤包括：利用堆焊的方法焊接出最小尺寸结构的非光滑表面，为较大结构尺寸预留出位置，堆焊后利用磨床对焊接结构进行修正；对附有最小尺寸结构的触土部件再次进行堆焊处理，焊接出次小尺
