Sir
I think so whatever the matter You are already given i.e good but my sincere request is that try to add some examples like
hot rolling::::::::::::: roll piercing and ring rolling
cold rolling:::::::::::: thread rolling and gear rolling
along with that If u add
where T is the melting point temperature of the metal
cold working processes--- < 0.3 T
warm working processes--- 0.3 T to 0.5T
hot working processes--- 0.5T to 0.7T [or > 0.5T]
then it is understandable to every student those who want give presentations like me...
