ABSTRACT
After reading this chapter you should understand: (a) what is meant by hot, cold and warm working of metals (b) how industrial steel sections are made by rolling (c) the principal methods and benefits of forging (d) the importance of the metallurgical effects caused by rolling and forging processes (e) the basic differences between rolling and extruding metal (f) what is meant by cold drawing (g) the way in which bar, wire and tubing are made, and how the mechanical handling
problems involved are overcome (h) why components are made from sheet metal (i) the two fundamental processes involved in the production of most sheet metal parts (j) the benefits of fine blanking (k) the effect of applying shear to a punch or die (l) what press tools are and how they differ from transfer tooling (m) the basic difference between sheet metal bending and deep drawing (n) how spinning, shear and flow forming differ from other sheet metal processes.
