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.

2- A chain drive using bush roller chain transmits 5500 W of power. The driving shaft on an electric motor runs at 1440 r.p.m. and velocity ratio is 4.6:1. The drive is required to operate continuously with periodic lubrication and driven machine is such that load can be regarded as fairly constant. Considering the center distance to be as minimum as possible, design the chain drive by calculating leading dimensions, number of teeth and length of the chain.
