| Question | Answer |
| Casting | Definition Casting is an object being made by pouring molten metal or other material into a mold. |
| Forging | Definition Forging is to make or shape (a metal object) by heating it in a fire or furnace and hammering it |
| Spinning | Definition Spinning is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. |
| Extrusion | Definition Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. For example it would turn a circle into a square |
| Drawing | Definition Drawing is a metalworking process which uses tensile forces to stretch metal. As the metal is drawn (pulled), it stretches thinner, into a desired shape and thickness. |
| Deep Drawing | Definition Deep drawing is a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention |
| Rolling Process | Definition The Rolling Process is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. |
| Bending/Folding | Definition Bending/Folding is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. |
| Pressing | Definition Pressing is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. |
| Punching | Definition Punching is a metal forming process that uses a punch press to force a tool, called a punch, through the work piece to create a hole via shearing. The punch often passes through the work into a die. |
