Basic types of sheet-forming processes include: Select one: O a. Stamping and forging O b. Shearing, bending, drawing, and forming Oc. Extrusion and bending O d. Moulding and casting
Determining how much the blank-holding force should be applied in deep-drawing depends largely on: Select one: O a Type of the material, productivity to be achieved, worker's attitude and component geometry O b. Type of the material, thickness of the sheet metal size of the metal blank to be drawn, and component geometry to be formed Oc. Type of the material, thickness of the sheet metal, size of the machine and speed of the machine O d. Type of the material productivity to be achieved, speed of part handling and machine size
What is the "springback" in sheet metal forming ? Select one: Metal jumps fast when the force is released O a. O b. Metal cannot go back to the initial thickness Oc. Metal recovers elastically to the original shape due to the release of the force O d. Metal recovers plastically to the original shape due to the release of the force
