Rapid forming method and device for multi-axis and axis variable zero component

The invention discloses a rapid forming device for a multi-axis component and an axis variable zero component. The rapid forming device comprises a fixed base, a first stand column, a gantry crane, a composite moving platform, a workbench, a rotating cross beam, a linkage cross beam and the like. The rotating cross beam horizontally moves relative to the gantry crane cross beam; the linkage cross beam rotates relative to the rotating cross beam; the material adding module and the material grinding and cutting module synchronously and horizontally move relative to the linkage cross beam; the gantry crane beam moves up and down relative to the gantry crane stand columns. The composite moving platform can horizontally move relative to the fixed base, first stand columns are arranged on the outer sides of at least two end portions of the workbench, the first stand columns are fixed to the composite moving platform, and the workbench can obliquely move relative to the first stand columns. The invention has the adv
