QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
Aligatoring - ANSWER In a complex phenomenon and maybe be caused by non-uniform deformation
during rolling or by the presence of deflects in the original cast billet.
Headers - ANSWER Heading processing can be carried out cold, warm, or hot; they are be performed on
machines called
Heading - ANSWER Is essentially an upsetting operation, usually performed at the end of a round rod or
wire in order to produce a larger cross-section.
Hubbing - ANSWER Consist of pressing a hardened punch, having a particular tip geometry, into the
surface of block of metal
Skew Forging - ANSWER A process similar to roll forging
Incremental Forging - ANSWER Is a process in which a blank is forged into a shape with a tool that forms
the blank in several small steps
Isothermal Forging or Hot-die forging - ANSWER The dies are heated to the same temperature as that of
the hot workpiece
Swaging - ANSWER A solid rod or tube is subjected to radial impact forces by a set of reciprocating dies.
Forgeability - ANSWER Is generally defined as the capability of a material to undergo deformation
without cracking..
Perforating - ANSWER Punching a number of holes in a sheet
Lancing - ANSWER Leaving a tab without removing any material
