Typical forming PROCESSES are:RollingExtrusionForgingDrawing233 Forming PROCESSES Forming PROCESSES --RollingRolling--Rollingis a process of reduction of the cross-sectional area or shaping a metal piece through the deformation caused by a pair of rotating in opposite directions metal gap between the rotating rolls is less than the thickness of the entering bar therefore a friction force is necessary in order to bite the bar and to pull it through the rolls.
