- i need the answer quicklyarrow_forward3XPL@!N THE PROCESS @ND PROVIDE EXAMPLES FORMING OPERATIONS 1. Forging is mechanically working or deforming a single piece of a usually hot metal; this may be accomplished by the application of successive blows or by continuous squeezing. 2. Rolling, the most widely used deformation process, consists of passing a piece of metal between two rolls; a reduction in thickness results from compressive stresses exerted by the rolls. 3. Extrusion, a bar of metal is forced through a die orifice by a compressive force that is applied to a ram; the extruded piece that emerges has the desired shape and a reduced cross-sectional area. 4. Drawing is the pulling of a metal piece through a die having a tapered bore by means of a tensile force that is applied on the exit side.arrow_forwardExample Problem-2 A cylindrical rod of non cold-worked brass having an initial diameter of 6.4 mm (0.25 in.) is to be cold worked by drawing such that the cross-sectional area is reduced. It is required to have a cold-worked yield strength of at least 345 Mpa (50,000 psi) and a ductility in excess of 20%EL; in addition, a final diameter of 5.1 mm (0.20 in.) is necessary.
