| Abstract Scope |
Spin forming is a manufacturing technique for creating axi-symmetric geometries by iteratively shaping a metal blank to a mandrel. The success of spin forming methods relies on localized deformation initiated by one or more moving rollers: the degree and intensity of this localization are a function of process parameters and affect the macroscopic forming response. The use of CNC and hydraulically powered spinning machines allows for the forming of higher strength alloys and thicker section blanks at room temperature. Localized deformation challenges simplified assumptions about stress state and classic workability predictions that are traditionally used to guide process development. Here, we will review and consider the process parameter space for sub-techniques of spinning: namely spin, shear, and flow forming. Emphasis is placed on highlighting how microstructure and properties evolve, and tools for advancing process development through both analytical and computational techniques. |
