Explanation Cold-roll forming is an example of deformative process of gear forming. It involves the gear blank to be fed between the work hardened rolls. These rolls are gradually fed inwards while successive relatively rotating with respect to the blank. Cold-roll forming is the process which is usually done at equal to or slightly more than room temperatures...
