Concept explainers

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

In powder processing, a cylinder with a diameter of 2 inches and a height of 10 inches is to be made from fine copper powders. A single-action press is used for compaction. If the average density of the green product is 7 g/cm3 at the bottom half of the cylinder, estimate the compaction pressure at the punch surface. Assume no friction between the powders. The coefficient of friction between particles and containers is 0.2.
