2 Answer the following questions by circling True or False. 1. Open structures are used for precision forms and profile grinding. ( ) 2. In centre-less grinding operation, it is possible to grind cylindrical workpiece without actually fixing the workpiece using centres or a chuck. ( ) 3. Since all the machining parameters are built into the broach, very little skill is required from the operator. 4. The machined surface should be used as the clamping surface as it can improve the clamping stability. ( ) 5. During the measurement, a comparator is able to give the deviation of the dimension from the set dimension. ( )

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.
