The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. highspeed production takes place in the rolling.

Considering the influence caused by joint angle, nonlinear damping, and nonlinear rigidity, the nonlinear torsional vibration dynamical modeling of the multiDOF rolling mill's main drive system is established. To analyze the coupled equations by analytic method, the equations are decoupled by transforming them into principal coordinates. The amplitudefrequency characteristic equations ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
