Abstract: Thin-walled spherical shells are weakly rigid and prone to clamping deformation, which will affect machining accuracy. This work introduces adsorption clamping combined with traditional internal support clamping to form a support-adsorption composite clamping method, and proposes a clamping strategy based on the step-by-step application of support and adsorption loads. The spherical shell static response model is established, and the displacement analytic solution of equivalent constraint superposition is proposed by decoupling load and boundary constraint and Reisner force-displacement hybrid method. Then, the vacuum generation of the Laval nozzle and pressure regulation mechanism are elucidated, and the matching mechanism of the vacuum degree and spring support is revealed. Considering the coordinated optimization of support and adsorption deformation, a synchronous control method for linear interpolation of support and adsorption loads is proposed. The research results indicate that there is a significant clamping deformation in the top ± 10° range, and the maximum relative error of the prediction model is 12.4%. The larger the clamping force, the larger the deformation of the workpiece, and the optimal support load is 0.01 MPa, and the vacuum is 80 kPa. When the supporting load is 200 N and the vacuum degree is 80 kPa, the maximum clamping deformation can be reduced by 58.3%. The clamping strategy of applying support and adsorption loads step by step can reduce deformation during the clamping process by 32%. Under the traditional support clamping and the support-adsorption composite clamping, the average surface roughness after milling is 1.955 μm and 1.771 μm, and the wall thickness distribution is 4.75–5.13 mm and 4.90–5.09 mm, respectively. This work provides a new way for milling spherical shell workpieces. [ABSTRACT FROM AUTHOR]
