Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.

(USCS units) A part is hot forged in an impression die. The projected area of the part, including flash, = 17.3 in2. After trimming, the part has a projected area of 12.5 in2. Part geometry is complex. As heated the work metal yields at 13,000 lb/in2and no strain hardening occurs. At room temperature, the metal yields at 30,000 lb/in2. Determine the maximum force required to perform the forging operation. (use table 18.1 for Kf )
The quantity of work that can be done in the die may be used as a defining feature of forging processes. Please identify the following three broad classes that this sorting generates.

3XPL@!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.
