  Subject: Manufacturing Process I Unit 2: Metal Forming Processes Forming Forming is a manufacturing process in which raw material is permanently deformed into desired shape such that the stress induced in the work-piece is more than yield stress but less than ultimate stress.  Examples: Rolling, Forging, Extrusion, Press-working etc. Types of Forming Depending upon the working temperature, forming can be classified in two categories: Hot Working and Cold Working. Hot Working Hot forming is a forming process where the working temperature of the material is kept above its recrystallization temperature.  Examples: hot rolling, hot extrusion, hot forging etc.  Cold Working Cold forming is a forming process performed below the material's recrystallization temperature. Examples: cold rolling, cold extrusion, cold forging, press working etc. ______ Read more ...
