Sheet Forming Processes; V-Bending of Sheets is more expensive than Edge Bending. (T or F)In Metal Forming Processes there are 2 Basic Categories; Bulk Deformation Sheet Metalworking (T or F)In Sheet Metalworking there are 3 types of processes used; Bending Drawing Cutting (T or F)An Advantage of Hot Rolling is the process produces a final product with Small Tolerances (T or F)Direct Extrusion produces Hollow or Semi-Hollow types of Cross-Sections. (T or F)Designing a metal sheet product in the elastic zone of the Stress-Strain curve gives a longer life cycle for the products service (T or F)In the Bulk Deformation, Drawing Process, there is Tension Residual Strain. (T or F)Hot Rolling metal prevents residual stresses from building up in the made product (T or F)
Which of the following is a suitable process for creating a hollow 3D shaped component?
