Sheet Metal Forming: Processes and Applications covers all major sheet forming operations including blanking, bending, flanging, deep drawing, stamping, spinning, clinching, and crimping. It describes the forces, stresses, and temperatures associated with each forming operation, the equipment and tooling normally used, and the control of critical process variables. The process of conventional spinning has been widely used in the production of sheet metal parts, but nearly in all cases, the initial blank of the process has a circular shape.Conventional spinning: (1) setup at start of process; (2) during spinning; and (3) completion of process 53. 4.
