Fast automatic processing method utilized in lathe and milling machine for large thin wall part with cylindrical grids

[0011] The technical method of the high-speed turning and milling of the cylindrical mesh of the present invention is further illustrated in conjunction with examples. For example, processing, a thin-walled part of a rotating body with a diameter of 1500mm, a wall thickness of 6mm, and a height of 450mm. Such as figure 1 As shown, the inner surface has a cylindrical grid structure. Using an elevated five-axis linkage processing machine tool, the first step: first process the reference plane, outer circle and inner hole of the part; the second step: forming and processing the cylindrical grid, using a φ20mm TiN coated four-tooth finger milling cutter, the tool The fast forward speed is 45m / min, the tool speed is 12000r / min, and the cutting feed speed is 2.5mm / s. High-speed wind cooling is adopted, and the wind pressure is 5-6Mpa. At room temperature, the tool continuously processes the cylindrical mesh according to the processing program. The trajectory of the tool moveme
