Die-less spinning has high flexibility in aeronautics, aerospace vehicles and other manufacturing fields; however, the wall thickness of the workpiece is hard to control in die-less shear spinning. A flexible control method of wall thickness distributions on the truncated cone shape is attempted using double-sheet shear spinning. The fundamental approach entails the adjustment of original thickness...
Along with the development of digital manufacturing level, to eliminate digital measurement error becomes very important in the production and manufacturing process. In order to effectively eliminate measuring datum error, a novel algorithm for digital measurement error rectification is proposed. According to the principle of graphics transformation, a nonlinear objective function with constraints...
