— 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 cross-sectional area.. The types of rolls used in rolling mills depend upon the shape, size, and gap between the rolls and their contour. Because of workability and limitations in …

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
the mill retain the coarse material for further processing while allowing properly sized material to pass through. 4., heavy material such as stone, glass or metal can exit the mill Hard via gravity. Lighter or low density materials such as wood and paper may require pneumatic suction for effective discharge. One size does not fit all
