The word "Manufacturing" is derived from the Latin words manus (hand) and factus (make).
In engineering, manufacturing refers to the application of physical and chemical processes to alter the geometries, shape, properties and appearance of a starting material in order to make and assemble it into a product. As the definition suggests, it is not only the material, but also the process that actually determines the shape and microstructure of a component, and in turn, the overall properties of the material. Thermo mechanical manufacturing processes are routinely applied in industry to improve or enhance material properties, eg. rolling, swaging etc. Here at IITK, we study in great detail various manufacturing processes and their correlation with structure-property of the material. Some of the processes which are being looked at, in great depth, include conventional processes like Rolling, Machining, Swaging, along with non-conventional processing routes like Constrained Groove Rolling / Wavy Rolling, Constrained Grooved Pressing, Equal Channel Angular Pressing.
