“…Nguyen et al [5] considered the geometric parameters of the bending process by Taguchi's orthogonal array and established a finite element model of the copper elbow to predict the forming quality. Jiang et al [6] studied the rotary drawing formation of a large-diameter thin-walled tube via the finite element method and designed a bionic elastic mandrel for multidie constraints and multiple forming defects. Wu et al [18] used finite element simulation and five kinds of the experimental mandrel on the quality of the elbow.…”

“…However, pipe bending is a complex deformation process with a multifactor coupling effect coupled with the hollow structure of pipes; as such, many quality defects are prone to occur during deformation [2][3][4]. Therefore, many studies have been conducted on the pipe bending mechanism, the prediction of forming quality, and the proposal of new methods and processes [5][6][7] to improve the forming quality of common pipes. However, new bending methods and processes have certain limitations.…”

“…The destabilization and cracking problems are difficult to suppress for both molded spinning and the center-restraint mandrel-free spinning process, especially for the thin-walled blanks with large diameter-to-thickness ratios. To address these issues, a marginal-restraint mandrel-free spinning method is proposed [27][28][29][30][31][32][33][34]. As shown in Figure 3, the blank is fixed circumferentially to the cylindrical support fixture with a press plate to achieve the marginal restraint, and it rotates on the spinning machine's table with the cylindrical support fixture.…”

“…As shown in Figure 3, the blank is fixed circumferentially to the cylindrical support fixture with a press plate to achieve the marginal restraint, and it rotates on the spinning machine's table with the cylindrical support fixture. Compared with molded and mandrel-free spinning with a center restraint, the trajectory of the roller moves To address these issues, a marginal-restraint mandrel-free spinning method is proposed [27][28][29][30][31][32][33][34]. As shown in Figure 3, the blank is fixed circumferentially to the cylindrical support fixture with a press plate to achieve the marginal restraint, and it rotates on the spinning machine's table with the cylindrical support fixture.…”

“…In the aerospace and military sectors, high-precision measurement of inner diameter has long been a significant aspect of component manufacturing inspection and a challenging challenge to address [1][2][3]. Contact measurement technology [4], such as coordinate measuring machines (CMM), has a high degree of precision and a wide measurement range and can execute the inner diameter measurement duty with the greatest accuracy [5][6][7].…”
